What is your definition of a "good" class?
Sure it is now not as buggy as it used to be.

Faction, as both faction has its ups and Downs usually ppl role Ally for pvp and Horde for pve.

As for realm, if you are a 'hardcore' pve choose Lordaeron. But if you are a casual player and looking for fun but still have life outside WoW choose Icecrown.
