Unfortunately by putting thrash as a level 81 skill and giving swipe a 6 second cooldown they destroyed druid aoe tanking at lower levels. I think they are hoping to fix some of that by making the cooldown on swipe to be 3 seconds instead of 6 in the 4.1 patch. I am not sure that even that will fix it although it will certainly help. They may just say that it is good enough anyway since they mostly focus on how druids are doing in endgame content.
