Honestly, I'm seeing very little of WPVP in warmode. Only had a few encounters and my pallies (1 prot 4x ret) are performing decently well.

An anecdote would be when I had a group of 7 people from the same guild jump me while gathering. Got 3 of them before I dropped. They stuck around so I ressed on them and wiped them. Then a seemingly immortal resto Druid rocked up. Could not get him below 90% in a full stun... Healers seem a bit over tuned currently.
