Classes with most fun/strong pvp while leveling?

[Kramer]

Im going to level another character and i want to know which classes you feel are most fun to pvp with during 20-50ish?

mage
warlock
rogue
paladin
shaman
warrior
priest

(i already have a hunter and a druid at 60)

I have lots of gold that i am willing to spend to keep my character in good shape and will be leveling engineering to go with it.

[heyythere]

how is hunter and druid at 60?

I suggest mage if you wanna do pvp, at least with keybinding, they are fun

[Sham]

Imho the strongest for leveling pvp without twinking are rogue and warlock
