@dragonfly; no cuz if you lose a battle, your faction loses points in the war, so the point of only getting stuff if you win is so that your encouraged to try and actually beat the other faction.
@saboku; yeah, in the arena it doesn't matter, but in faction play a good defense deck is really important since if you lose battles, your faction loses points.
kelenestus; i went with an xbox style layout- WASD for movement, l/r arrows for looking around, up/down arrows for looking up/down, spacebar for shooting, enter for jump, and q for switching weapons (dunno about how good that is, since i always use the hotkeys).
