From my experience at the lower levels in beta, PvP seemed bland. Since this was the lower levels, I just have a few questions for high end PvP:
a) Are there any 'invulnerable' abilities like paladin bubble/mage ice block/cloak of shadows for various classes?
b) are there movement effects like sprint and blink?
c) Any interrupts at all?
and finally will Assassins get a vanish at higher levels? the stealth is fairly broken (i know it's beta but still).
Cheers
