I was looking at a Druid+PD+CUP+SM+TG team. SM/TG can be freely replaced by other 1000 attack rate heroes. All heroes have 5/9 skill and no talents.
Without a cap on attack rate, PD will stack on more or less infinitely. 30 seconds into the fight, your team will be buffed with 8xPD, 6xDruid and 1x Cupid buff for a total of +4143% DMG, -94.24% Attack Rate, and +716% MOV SPD.
Something seems way off here (or the no cap on attack rate assumption is wrong)? I have 5/9 skill or higher on those heroes (7/9 PD) and don't get anything remotely close to this 30 seconds into a boss fight.
