Hello.
I play WoW for some time and Id like to lvl with fun as ally, do dungs often, after reaching top lvl playing bg, winning arena, get items,etc...
In global channel of game chat i see abbreviations but I don't know 95% of them.

In Frostwolf im top lvl pally but can't win arena
In Lordareon im lvl38, fun but no dungs, disabled dungfinder and not many ppl
Icecrown- long queue

Which realm do you advice ? How can i get better gmeplay experience ?

Thanks
