True—drop is a tough one for flying objects. I found myself switching to boom a lot. I think soldier with all the rifle cards and sniper are better for those personally. Assault rifle accuracy is actually an impressive card when maxed out. I was surprised what I could do with a full blown lancer damage build last I tried.
I haven’t played much horde in a while—I don’t have a one X yet so switching from 60 FPS in versus to 30 in horde is always super annoying for me especially when I want to be sniper.
