New account: help me make a class descion please!!!

[a C e]

I have a new account and i have a scroll of resurrection from before. ( 1 free level 80) so i have one choice
I want to play competitively so i need to choose a main that is viable for 2.2k+ in arena and rbgs

I decided to level a class i never played before in pvp?

my three choices are shadow priests, warlock ,warriors and enhancement shamans.

I enjoy playing all 4 classes so i dont mind picking one over the other, but i want this character to be viable and wanted in different comps and rbgs groups.

and please elaborate why you picked that class.

I have good experiences as holy paladin, mage, dk and rogue.

if i wanted fotm i would go for monk, rogue or mage. i just want peoples opinions on what is good and viable beacause there are some classes that arent in a good position.
