First impressions new maps are decent, though running around on Jade can be a bit of a nightmare if you've low shields/health as you're very vulnerable to distant fire. Tactically you're best to hold the upper level, and only go down if you have to. Goddess seems pretty fun, but can be a bit of a nightmare if the enemy have a few turrets up as there are some long views through the central space which is a hold point).
Only unlocked the Vorcha soldier so far. Seems pretty fun (flame thrower is nice), but takes getting used to. JG seemed to enjoy it.
Tried out the funky new Krysae Sniper Rifle, which just seems a tad OP. Maybe it's just the gib effect, but the gun seems to totally destroy pretty much everything.
