which better for pvp fire or frost

hi guys i want to start playing pvp and im rly confused which spec i should start
so what is your advice for me ?

All 3 spec are good if you know to play them, but frost is main arena spec

Frost is the first one and the more pvp orientated for arenas.

Fire is the second one, squishier and pretty good in 1v1's

Arcane is the more pve orientated, you can still pvp but it can be difficult, takes lot of practice.

Frost is the easy answer, most will say am an ***** now but arcane is a REALY strong spec in 1v1, with bauble and engineering. It needs alot of practice though, timing invi and burst with extra sp from absorbs etc.
