In PK their available tactics are dull and uninspired. Ganging, tripping, buggy ass mounts, just all so very dull, and I couldn't bother to prep at all, so once I hit 40 95% of my fights were utterly one sided.

You play a goblin to get to be a goblin. You can have a lot of fun RP'ing that when you get past the whole I need to win PKs aspect.
Dwunot was easily in my top 3 most enjoyable characters to play, and I think largely other players had fun interacting with a char that they knew the player of in no way took himself at all seriously, while my character put on the airs of being the most important person in Thera. The self-proclaimed king of silverwood is one of the best titles I ever got.
