You should make a starter-hand which u can combine, so that there is more strategy and less luck involved... And btw if u run out of monay, just make a new acc and do the 4 quests, that'll get u started again...
Hmmm... I play at challenging so I dont know exactly how hard heroic is, but here's what I do know: the healer doesnt do anything, u'd best leave him alone... that leaves 2 tactics 1 take out the captain immediately by dmging him untill his life is just above half and then stun him and dmg him untill roald says lets get outta here... 2 silence the captain and dmg the sniper with all uve got only using stun wehen he has both crouch and the other dmg increasing buff on and afterwards taking out the captain... its best to use ure party's relentless mode unless ure getting heavy dmg, then u should put veradux on tactical... I hope it helps, it does for me...
.... after 1 hour it's not called owning anymore... it's just a sad victory... but which difficulty r u playing on? I might have some advice if u need it...
