Race-changed from Orc to Troll, was well worth it ! I enjoyed playing Troll for a long time, it stands out even more than the Orc. The racial was very strong. I wish I was Troll for Northrend Beasts in ICC. flat +5% damage agaisnt beasts. Anyway. Many good times were had. I eventually race-changed to Goblin when Cataclym came out. Played for a few months. And finally reverted back to being an Orc :)
I had twink rogue undead and blood elfs I prefer for Paladins and not much else.
