I just spent 15 minutes in a battle agains a single rare Magic affinity level 57 opponent with a team strength of 17k.  My team power is 87k with a 50 Force Epic Attacker, and three level 60 champions.  Two are Spirit so I can see their attacks being reduced but to do less than 1k unless I was luck enough to get an armour reduction (or any debuff for that matter) to stick.  I know the system must do something to boost the defending side, as is evidenced by the fact that they always seem to get to go first and shoot off all there buffs, debuffs and area attacks.  But to allow a single defender with that great a discrepency to be that tough to beat?  It would indicate a degree of hit points, defense and resistance equal to wearing three armour sets at the same time.  Not to mention seeing him routinely get to take three to four consecutive turns due to extra turns being dolled out.

System broken much?
