Okay first of all this is ehemmm a whining thread But I mean no offense though, this thread aside from being a whiner also serve as summary of all these 2 years playing dark eldar who are made by Phil Kelly. So let me explain my experience playing the dark eldar.
So incase you are wondering, dark eldar are actually unique in that they are a 'piratical' armies, rely on speed, low number, low defensive capabilities and should have been 'high' offensive (close combat) attacks. The current codex design have succeed on the first 3, but failed on the last which is bummer. On the 6th edition, it become even more bummer with current fleet rules, which on 'speed' term they have reduce effectiveness. It is indeed as phil kelly said that dark eldar are glasshammer but I would rather said a dull glasshammer as they are lack offensive power.
So that's explain the general, let's see how the meta gaming of competitive gameplay. So let's play where you are bit on warrior stuff, back up by ravager and few reavers and incubi elite. End result? bummer, against horde type armies (ye don't have enough offensive to destroy all of them in single strike, pretty much the unit number you have to deal against them, I'm looking at you imperial guard ) , bummer too against vehicle armies (power from pain are useless as you don't get pain token fighting against this type of armies, blood angel and imperial guard... and with even bigger problem when you actually face this army as flyer... the necrons), and also against the armies tailored against dark eldar (yep flamers and lascannon/autocannon spam, you face against this type of dude in all type of wargamings, can't blame them for just wanting to win 'perfectly' against you but it's perfectly ruin the spirit of the game where you are suppose to enjoy the game instead being one of them annoyed... the only facing this dude is to have another armies by not telling which race you are playing against them, and I still don't make them yet). So indeed the only way for dark eldar generally win with any type of army list is when your enemy field in low number units (grey knights being one of them), but the ONLY way to win as dark eldar (I can even said the ONLY LIST to win) is playing venom spam armies. This is one hell of dilemma as dark eldar to win in competitive environment MUST use a venom spam list in order to win (even then you MUST have a damn good luck on those CCW attack rolls! They are just like have S3 against T4 at all times!)
Off with generals and Metas, let's go to unit usefulness list. Minus the special character.
Archon > useful (for a good reason)
succubi > this are pretty shabby, but it's cheap, but still can't tackle those other characters moderate
haemonculus > cheap and otherwise useful for pain token, but little bit bummer in 6th edition as feel no pain take on 5+ moderate
royal court > in 5th useless, in 6th a little bit useful because incubi power weapon no longer kill those 2+, might as well max the number of attacks against them. moderate
Incubi > 5th are greatest, 6th wot the heck... AP3? are you kidding me? terminator win all arounds and only klaivex can kill them bit useless now
mandrakes > 6th edition give this guy a big pain instead garner some pain as outflank can no longer assault when arrived, USELESS
grotesque > great on pain token but still take pain on 6th edition with feel no pain 5+, moderate
wracks > same as grotesque, moderate, this also one of the unit to be carry in venom spam list as most people bring them for their T4 (useful)
trueborn > one of the unit that will be carried on venom spam list, useful in them, useless in other type of list (I count useful for purpose of counting them)
bloodbride > owww expensive, high attacks and they are so dead when their transport is gone, useless.... walking? not very good option eh
warrior > same as bloodbride
wych > same as bloodbride
Reaver > one of unit include in venom spam list usually carry by the people, is a top notch unit that can take care most unit in 40k galaxy, provided they are not shot first
hellion > almost same reason as bloodbride, but they have better save at least blarrghhh (useless...)
scourge > moderate unit, would have been best if they are cheaper but we are talking dark eldar in here man... low number count units
beastmaster > 5th a little bit sucks, but in 6th they are better provided they are not shot at first.. moderate in my opinion
ravager > one of unit usually include in venom spam list, useful at anytime as they cheap and good tankhunter
razorwing and voidraven > oucchhh this two flyer dudes, not only very expensive they are extremely weak, even if those single autocannon shot get hit them, you better pray they are not getting those 4+ result on damage table, bit useless now in 6th ( two useless)
chronos > anyone still play this? although useful for garner cheap pain token, this dude are useless when fighting all vehicle armies (where the heck they can kill to get those pain token useless in my opinion)
talos > moderate, your basic monstrous creature that are use as beatstick provided they can reach them in first place... bummer...
raider > most expensive transport you ever seen in 40k universe, and also most weakest of all of them. man even a bolter fire can kill them in 6th! useless
venom > this is the only unit that gave a big win to dark eldar, as they are cheaper than raider and same armor value as them. you can field them in large number and still can swathe all those infantry unit with ease...
so let's count the number of useless, moderate and useful.. that will be 9 useless units, 7 moderate unit, 5 useful units (these are unit include in venom list, the only way to win) . So in designing unit, dark eldar are bummers yerggghhh
So conclusion... dark eldar are becoming increasingly weak in 6th edition but that's only because they already weak in 1st place. Phill kelly failed to deliver what he would called glasshammer as he forgot to increase offensive power (most unit don't have them, the only who has it is archon, incubi and royal court). My hope is for future updates for dark eldar (either codex or FAQ if they are wanting it to change it immediately) that the glasshammer style armies can be reach for phil and GW. And as for you guys, is there any counter-argument or some backing argument to what I said? Discuss....
