I seem to remember a lot of hopping in warhawk too...
I always hop in Warhawk, but it doesn't really help as much as Starhawk does because of the auto-aim, its just more of a habit thing in Warhawk.
And to the other guy, I've been doing the grenade RPG combo thing in Warhawk since like 2008
I'm pretty good at Warhawk, almost a 2KDR, 500 in the world, etc, I dont know why I am so bad at Starhawk
hopping in wh helped, but not as much as in sh, especially in conjuction w/ snap aim. I pretty much hop in all TPS games, but I definitely picked it up in wh, which was my first MP game.
