ALL VTs/VEs heal/regen the ENTIRE group. It rocks.

And yes, the entire party would get healed for 1.5k. With all 4 priests spamming damage, I usually don't have to shift out to heal my pally buddy unless he's taking 1.5k damage every 2 secs. And his mana never moves.

Of course, this all sounds well and good but you can't really do mad healing through VE in PVE or you WILL get aggro and end up smooshed. Now, dropping VT+VE+SW:P and then casting renew on the tank will work great on all but the most lethal bosses in non-heroics. We haven't tried a heroic, so I can't speak to that.
