We all know that pvp isn't as balanced as it could be at the moment, what I personally believe to be the single most annoying thing is how spell cast is interrupted every time the caster is hit. I do agree that casters are incredibly strong in pvp, but I don't believe that they should be interrupted EVERY HIT (especially from bards.) The focus should be on how to make the game play more smooth, it just feels clunky when your can't actually cast anything. Some sort of spell shield, or some sort of buff is a much more appropriate way of dealing with those pesky casters. Perhaps give the healers a type of reflect spell to be placed on an ally, or maybe a pvp specific way of cc'ing.
