If you run with a druid healer in arena, you open with a sap, the burst one down(should be possible), then move to kill a second or vanish and reset your fight. Then repeat and your druid joins the fight with a cylone and needed heals.
After that you still have cloak of noobs and vanish to survive some inc damage. You will also have 4 blinds which you could target to arena frames.

I think once you master the rogue`s they can be very strong. Bad part of a paladin team seems that they need to rush in, every team knows what will happen. Rogues seem to offer more options to start and do a fight. Bad part is that they don`t have own heals and can die faster.

By just looking at the skills it looks like it has arena potentional, the future will show if they have.
