Ahem!
Instead of having to enter a menu to revive a dead party member using a spark(which could cause you to get hit in the process), why not have the same "pickup system" as before where you would walk near the party member and give them half your health but revive them with a spark instead.
I know you could just wait until after a fight to revive them but where's the team effort in that!
Either that or just put a 1 click button next to the dead player's portrait to spark em.
problem is you can accidentally "waste" the spark, something that not everyone (me included) wants to do.
+1 as an option. if problems arise, 2 clicks.
