I'm really digging Mech Eldar! I made the decision to swap over from my Death Guard shortly before the Waagh, and did reasonably well (4-1 on the Tourney) but a little short on points. I found myself - all but one game where I got smoked due to good playing on my opponents part and poor playing on mind - being able to deny my opponent objectives - and able to get 2 of the objectives and struggling for the others.
Here's how it wound up:
Game one vs. Foot Slogging Eldar 9-0 total points. I could not kill either 1 remaining warlock or 1 disabled war walker for an additional 6 points.
Game two vs Blood Angels 15-0 - speed and mobility carried the day here - but it was a hard fought match.
Game three vs Khorne - 0-20 points - got smoked. Bad tactics here on my part kept me from pulling much.
Game Four vs Bike Marines 15-5 game for me - good tactical hard fought game. Much closer than end score showed.
Game Five vs Blood Angels 16-0 game for me - another good hard game - speed and mobility ruled the day.
By Day Two of the tournament - I was starting to hit stride more with the army and "feeling" better playing it. I did feel as if I was missing something though.
After discussing the list with my good friend Sabote (who won the Overall at the Waagh with Space Marines - but also plays a hard Eldar list), he suggested that I have a lot of small units - but lacked a big "Punch-In" (free kudo's to 40K Radio) unit. So tweaking things a little. Thinking about dropping Falcons for all Wave Serpents - and going with a bigger squad of Banshee's. Fortune and Doom going with them to make it even better. I'll be playtesting several builds soon and will update on results.
