Mate, would be a much better world if everyone looked out for the overall community rather than trying to screw everyone out of their last bit of plat. IF and this is only and IF mind you, ppl put things on AH for a price that THEY would pay for it, it would show a marked change in the economy, make it a bit more realistic.
Truth of the matter is that it doesnt matter to majority of population whether you want them for guildies or whatever, that seems to be the nature of ppl.
Which is better, to have everyone on a server adequately equipped so when you want to run a raid and need to PUG it, that you can find ppl with all the right gear, OR screw the last bit of plat out of someone so that they dont have anything that is needed and you blow a raid because of it.
I know which option i use.
Short answer is that majority employ a greed before need scenario. And that is where the generosity is lacking
