the only real classes that need adrenaline are DPS that lack pawn (cuz sometimes they need to move 1 ap and it'll make them unable to do significant actions on their turn. and combo characters (for example right now I play as blood mage in our company and even with elemental affinity and elf I need adrenaline to finish my combo on a round1 (though I think i'll just take glass cannon and ditch scoundrel to get even more damage)
so if you're playing 4 of those characters - no wonder you need adrenaline. our rogue and tank don't need it. they either can wait a turn for a combo in invis or just don't deal significant damage to justify the need to steal ap from the next turn.
besides adrenaline was already been nerfed. it was just +2ap iirc.
