Well, Armor Abilities are fine. I actually also like armor lock. It's a defense tactic, and a pain for your enemies.
Like Twinreaper, 3/4 of people,as an example, don't know what bloom is.
Also good point here. I dislike how there's a Gausshog in Anniversary BTB. And the only chance of survival is if the Gauss is immediately targeted and destroyed. Or if you have a really good Banshee pilot. Still though, i think it's nice to see the Gauss' return.
