I've found you just cant be as frustrated when you die in this type of game, you must expect it, because it's wild gameplay.
I've found it very easy to be frustrated...
Whoo boy this game had me frustrated at some points. If your team is stuck progressing in a map. Usually its because they don't look for alternate routes. Take a new route, flank the enemy. Log jam busted.
Easier said than done of course. The climbing on stuff and spotting routes. These take a while to pick up.
