Nostalrius Begins - Quality wow vanilla realm (1.12)

I started to play Shaman few days ago and i find it really nice and fun class, for spec im doing enhancement shaman.
How is enhanecemnt shaman for PVP and PVE, for PVE i can also do Restro shaman but manly i want Enhanecement.
How is Shaman in late and is it worth playing it?
TY for help

Shaman in PvE is viable only as restoration. Enhacement and elemental are fun in PvP. Everything is known about the game and you can read up everything. Feel free to whisper me in game.
