But again speaking to 19 PvP as casters vs melee.

Don't waste your time. Seriously. You will go in, get your entire team 5 shotted by a super twink rogue that has 1200+ hit points and all sorts of armor and weapon buffs. And you will have 300 hit points and no armor.

Oh and your spells do 5 - 10% of his health. All 5 of your spells. You can load them up with a full round of dots and it will not even kill them.

If you want to PvP at level 19, figure out a way to melee. Maybe hunters.

But don't waste your time with cloth at 19. It is seriously unbalanced towards melee classes. 29 isn't much better.
