Great Bat rep as always.
Couple of suggestions for bad though that may have helped turn this one into a win:
1) Dragons. Coming out on T1 Dawn of War against the Storm Chickens was bad. Mmmmkay? Not gona harp on this, cause I'm sure after they failed the roll to see you were already kicking yourself. I'll only say that you have to be conservatively aggressive with your dragons. By that I mean, they're gonna die the turn after they disembark so you have to be virtually certain they kill what they shoot at when they come out. Gotta roll for sight to shoot with em? Screw it. Dance the serpent around till the next turn. 2 squads of dragons basically not firing before they died either lost you the game, or made it insanely more difficult to win.
2) Tank shocking. 11:10 on the video, you have two mobile serpents sitting around an objective with two squads of avengers sitting on the objective, and that nasty termy squad right next to em. Leave the avengers on the objective, then tank shock the hell outta the termies with one serpent while using the other to block them out. May have helped you hold that objective and get the tie (assuming the dread in back didn't kill your serpents. That tin can was on fire!) Also, probably could have done the same thing on the other objective (12:20 on video). May/maynot have been a huge issue there, but if you can stay on the objective, tank shock that termie squad and the dreadknight, and still make sure they gotta roll 6's why not?
3) Autarch. Saw you grabbed that fusion gun. Then he took down that dread, like a boss. You mentioned taking the farseer, and your reasoning is solid, but you may wana try and keep the autarch as well and find the points for the farseer elsewhere. That extra fusion gun running around is always handy. Either way, it's a tough decision with our codex being overcosted
atm, since whatever you get rid of is going to cost you a lot (in terms of points, and flexibility).
Other than that, great bat reps as always. Don't get discouraged with Eldar. Especially with codex creep eating at the army, it is a very fragile army to play, and if something goes wrong early it can be an uphill battle. Not whining about Eldar being underpowered or anything, in fact if the codex doesn't change at all whenever
GW gets around to updating it I wouldn't be surprised. Only real issue with it now is the inflated points cost on just about everything.
Anywho, keep at it. Eldar are definitely a difficult army to master, but a blast when everything works just right (or PITA, depending on what side you're on

). And
def keep those reports coming.
