Two problems with with the monk dps went UP logic ...
1) You're assuming monks and non-monks are attacking "helpless" mobs at the same rate. FALSE. Monks (especially the light variety) are constantly attacking stunned mobs whilst other melee do so only occassionaly ... this holds true even for "tactics" spec'd melee. Epics with a CC caster stategy might make it more even.
2) However, you're also looking at the changes from only the "epic" perspective. There are 19 other levels that these changes impact ... monks are LOSING dps relative to other melee. Going from "near constant" 200% damage to 150% is a big nerf. No other melee class is taking that kind of a hit. And before you say all melee are getting the same nerf ... SEE #1.
