The L1z1x are fucking sick!
Then again THEY aren't the ones that dropped four warsuns on my head. O_O LET ALONE A WARSUN SNEAK ATTACK!
WARSUN |\|1|\|J4 !
Anyway... I call the Yssssswhateverarr;lakjsf;dljk;zall.

The L1Z1X are decent, but they have a lot of disads to go with their advantages. Like - in a side-by-side with the Sardak, they get 1 higher resources to start, 1 lower influence, crappier trade agreements (1/1 vs 2/1), 2 more tech, 1 more command counter, 3 extra fighters, and a dreadnought. Pretty rank. The Sardak's special ability, however - is much ranker - they get +1 to everything vs. +1 to Ground Troops and Dreads, and 1 cheaper dread production. Honestly - it would be a toss-up for me which I picked.
Compare to Barony - Barony has one more influence, one more resource, 2 less tech, slightly fewer ships, and in my book a crappier power (+1 to all ships, or +2 to GC for 1 round for 2 trade goods). Honestly - arguments can be made for either being better.
And really, looking at all of them - it is like that. Except the Mentak. Mentak have 1 less resource, 1 more influence, equally crappy trade agreements, 2 less tech, less starting troops, and a crappier power (IMHO - they get two fire with 2 cruiser/destroyers at the start of combat, and very occassionally steal trade goods - big whoop).
So - honestly - the Mentak are broken. I think everyone else is pretty fair.
