Please do not use fluff to justify any kind of stats. Especially WS or BS of 5. There are other "well trained" or "super good" units with stats 4 (Marines, remember that 4 is an elite-value!). Making them 5 will lead to only one thing: More fanboy-GW-workers of other races will create their next Codex with stats 5 too and then everything will be where it is now (or worse if you think of Dark Reapers with BS5, WS3 compared to Space Marines with BS5, WS5!)
Use game-balance-views to decide what stats or gear should be useful or balanced.
Are Marines with Storm-Bolters and Force-Weapons for 20 points balanced? No. Should Eldar get equivalents? No, because it would be the same imbalance.
Are Henchmen with Storm-Bolters for 7 points balanced? No. Should Eldar get them instead? Nope.
I'm not saying that some Aspects or units aren't broken, we all know some are. But making weapon-specialists hit on a 2+ instead of 3+ is not elite-choice, it is unbalanced.
Neither I don't see what the problem is with Guardians as a concept. I'm not saying they should stay the way they are, no, they are expensive rubbish. But if I imagine a Craftworld, I think of millions of civilians. If they get in danger and get attacked or need to make a pre-emptive strike and have to
put in all their available strength, then I think of the same as when I think of the Imperium: A hand full of trained elite warriors (Marines, Aspects) among millions of normal forces (Guardsman, Guardians). That doesn't mean Eldar should consist of only Guardian-forces, but they should be a valid army-build same as an all-Aspect-army should be. That is possible right now. You can chose to pick 6*20 Guardians as your core choices or you chose 2*5 Dire Avengers. It is your choice!
Stop saying that because Eldar are a dying race, the concept of Guardians is wrong. It is not. If they need to defend their Craftworld, I imagine 90%+ of the forces to consist of Guardians. Small elite forces (or even big ones) aren't a contradiction here. It depends on the purpose. If you wanna play a scenario where the Aspects have been slaughtered in defence of their Craftworld, then you should be able to build up an army that consists only of mere Guardians. Removing this ability from the Eldar Codex would be the same like removing Gaunts from Tyranids Codex - a big flaw. They should exist and ever have. That they currently are not a valid choice is not a problem of the concept. In 2nd Ed you gladly took Guardians and they owned!
PS:
I noticed that Vampire Raider and Hunter are AV 10/10/10... made me cry on saturday. Guess I'll leave them just in my cabinets then
