ok ok. well the profession and stuff icons needed would be: mining, smithing, brewing (alchemy-like), skinning, jewelcrafting (not exactly huge gems, a little more modest), fishing, cooking, crafting (really general, make stuff from other items, starting from a mallet or fishing pole to chairs, nets, decorations for house, some primitive weapons, stuff that doesnt go under smithing).
at first i thought of using wow icons, but they dont fit to w3 that much. but i am probably using wow icons for that huge number of items (attachments) to be in game.
oh and maybe you have good ideas for other very important UI icons of a troll:
teach - ability for teaching the child some important things about life, a channeling ability that gives exp to child.
mate - for the male, nothing too vulgar please
something that would give on the idea, what that button is for.
mating on/off - for the female, to reject incoming male trolls.
