I had a recent little tournament. I used a fireblade, 12 and 6 firewarriors, 10 kroot, a riptide, 3 suits with loads of missilepods and the puretide chip, 2 suits brimming with plasmarifles, 2 broadsides with missilepods, 2 units of 5 pathfinders and a defence line with quadgun.
I lost a close game against enemy Tau with blood angel allies (his list was almost the same as my army, but no regular suits or aegis defence line) and for the cost he could fit in nearly two dozen marines and a rhino! Tsk. It'll surprise you how many marines you can spam if you set your mind to it. 50 marines is hard to shoot away, even with Tau.
Anyway, that first match was very close and tense. I had all my hard firepower at the end, except the two plasmarifle suits, but only 1 firewarrior on an objective. The unit of 12 with fireblade couldn't bring themselves to kill 3 marines in combat. I threw the riptide into hat combat as well, who killed 1 marine and then ran away.. while the firewarriors stayed to fight, and then got sweeped the next turn. Chicken riptide.. Anyway, that lost me too many troops so I lost on objectives, because the enemy still had a riptide, 3 firewarriors on his own objective, and 2 marines on another. Firepower is not everything, but I'm always too tempted by the prospect of a firestorm to invest more into troops than strictly necessary
The second game was rather.. unusual. The relic mission. I fought necrons, a lord, 30-40 warriors, 20 immortals, some crypteks and destroyers, and a ghost ark. By turn 3 more or less every necron was gunned down. I know how necrons work, and with such a ridiculously large supply of ap4 power I could easily destroy full units of warriors in one phase, without them having the chance to get back up. He was unlucky that when the plasmasuits blasted his immortals with the lord in the face with 5 or 6 plasmahits, his lord failed 3 3+ invulnerable saves and went down in one go, but by turn 4 the field was scoured anyway, so he'd have been unlikely to survive anyway.
The last game was against orks. A damnable unit of 11 lootas rolling 3 shots per model every turn. I shot them up quite well though. A unit of 5 nobs on bikes raced behind cover in the first turn (lost a model to my riptide's blast) and next turn was inches from my battleline. They got a full army of firepower in the face, then got the entire army again on overwatch and then (because they didnt make it due to the aegis line) they got shot up by everybody again! There was a battlewagon with 20 boyz hurtling towards me, but my missiles took it out from the side, and everything on the field was culled quite rapidly.
Nominated for best painted army, and got 4th place. I was there mostly for the fun of playing in a small tournament. I went with some members from the storeclub of my GW. Me and another even wore our club tshirts. We had a fun time, and I'm going there again in two weeks, with a clubmember (who's blue tau have been shown somewhere halfway in my blog) for a doubles tournament. I might finish my hammerhead with the hexagon pattern.
