You think 5, 20 second +15% boosts with a 10 second downtime compares to a static +10%? Really?
Should I mention the fighter 20 has a static 10% with 7 +35% boosts? that the ranger gets a whole extra offhand attack (5 in every time everyone else does 4), etc, etc.
Barb dps is great, and it applies to everything, but when you put a kotc3 pally in ideal circumstances, it tends to win by .. well, like 1% or something, its negligible. Then again, nothing else gets within 20 or so dps of either.
