Personal goal is to have fun. In order to do that, I cripple myself so that no matter how good I get there is always a challenge. (Hoplite spec, light armor, unorthodox weapon choices- Light Lance, Knife, cheap 1h axe)
Teamwork is always fun, as a hoplite I can always contribute to team fights. I like seeing others succeed so I feel all warm and fuzzy if I help a newer player take down a vet, or help a vet takes down 3-5 or more people at once. After the main battles over, I go and try to do hoplite duels which usually don't go well but are very fun. Also gives me a chance to die... once you get good at using a shield all that work you planned to do while dead doesn't really get done...
Note: I know I tw a lot, and I know some of you hate it. But I do feel horrible about it every time, so I do apologize in advance. I have good intentions, I swear.
