This. One hundred times this. One of the big reasons I think everyone's memory of ICC damage being ludicrous was the 30% ICC buff which actually might as well have been the unofficial 35% ICC buff due to crit scaling and fun like that. If you wanted an accurate depiction of end game dos for Wrath, you would 5 man Patchwerk 25. I know it sounds ludicrous, but a full raid would kill it far to quick to make any sense and Patchwerk is the perfect target dummy fight. Super competitive dps wouldn't really be higher than 15k in Heroic gear if people did that.
