Shouldn't 1 healer v 1 DPS be equal? They can't kill you, you can't kill them. That's balanced. Go 2 DPS v 1 healer? If you don't kill the healer your DPS probably don't fully understand their skills in PVP. Maybe they're using a knock back as a DPS skill, as opposed to an interrupt? Maybe they didn't use that PVE useless skill they'd forgotten the moment they learnt it?

'Cancel on damage' was beyond daft - It completely overpowered SCH in PVP compared to WHM. I wouldn't mind them bringing Moral back, taking damage while casting = push back casting bar, Moral = less pushback.

There is a lot of issues with PVP but this is not one of them.
