1) ...I'm not exactly sure what's with a lot of the posters here. You all sound like I've never played this game before. I have, and even if I didn't, I have figured out most everything there is to have figured out.
2) You think I don't want to trade stuff I find or haven't done so already? I have done that in a few occasions (I got a druid and assassin prime doing that along with torches), but whose going to trade with me now to get high runes or the best equipment there is? Certainly not players that are newer than me since they have nothing and yet they're most likely to be on, and I bet certainly not older players since 1) they are least likely to be on as often as newer players, 2) many of them either already have those kinds of enchantments that I have (and guess what they're probably not willing to sacrifice an annihilus charm they have just to use the enchantment thus going back to that point regarding torches and annihilus charms being completely tedious to get how many times now), or 3) they don't think its worth trading their high runes for them for whatever reason. So I don't so your point.
3) Yes, there is a build for every scenario. Yes a Necromancer can't do what an amazon does (maybe that's why they're two different things). but in the end of the day it doesn't amount to much if you don't have the proper equipment for them now does it? Why else do you think I prefer the necromancer in general? Because he's easy to use in general and getting good equipment for him isn't that hard (minus the trag trophy which can be a pain to find). Most other characters/builds are another story (especially the druid and assassin in general and anything but a shield throwing barbarian).
