DDO has become increasing centered around maximizing DPS... Other types of builds (tactical, stat-damaging, AC tanking) are considered sub-par....
I would like to suggest that for the next raid, instead of one bad-ass red-name immune to everything except DPS, we get a swarm of 50-100 orange-named monsters....
A raid where high DPS, poor AC gets hurt pretty bad, and where characters with high AC or trip, stun ability can do fairly well....
