Hey gang.
I've got a few premades on beta atm, and I just did a few random heroics on my recently copied Retadin.
I noticed 2 major things.
1) The damage is absolutely ridiculous. Mobs were hitting for almsot 60% of my hp (89k). The tank would almost get 2 hit in any scenario. Don't get me started on bosses.
2) Healers going oom in literally 12 seconds. They have to use the fast very expensive heal to keep the tanks alive due to the overwhelming damage.
That's pretty much it. I've attempted at least 50+ heroics and not once have I downed a boss due to tanks dying in a healcast or healers going oom faster than i can get a full rotation off.
Not happy at all.
