Considering most healers are too dumb to focus heal the people with battle high/battle fever I certainly do not want to see a means of dragging BH/BF people into enemy lines where they'll get destroyed simply because a tank could reach them with a provoke. That's a completely stupid suggestion for Seal Rock. I don't work on getting kills for a skilless tank to negate that so easily. I don't even want that in Wolves Den/Feast, because stun lock is annoying enough as it is, imagine you survive that and then get provoked (as a healer) for 3-5 sec more and you're gone.
Reducing the timers on tank pvp skills would be a good thing but are tanks really in a bad spot in pvp right now? I really doubt it, except for DRK maybe, who hardly help their PT at all (lol carnal chill).
