Donīt build these freakishly large creatures then or be prepared to have them run around with bathlets, swords or lirpas only.
STO uses the Champions Online engine I think. So these things are an inbuilt problem.
Also donīt expect it to be solved anytime soon, the smallish art department got bigger fish to fry.
Actually I'm pretty sure weapons can be size adjusted in CO, by altering the hand size of the character. I'll have to check next time I play.
Doh! No need as O_Farmer has confirmed it already.
