Nothing in particular, well maybe how so many of them complain no matter what. Like when Striking Scorpions weren't included in the tease release if classes, a bunch went straight to "let's boycott the game" and just general attitude they seem to be even more anal about things than the diehard space marines. Really it's just me shadowing rival factions and wondering if anyone else sees this trend.
Quite a few Eldar player aren't to happy with the fact that they can't play female Striking Scorpion or Male Banshee from rank 1. (In case you wanted more proof)
