i personally like the build for free system.i understand that one day it wont be that way, but i like to help someone i dont know,then they ask what do i owe you? ,i really enjoy saying nothing go have fun now.
i would much prefer this to other games ive played where as a new player i could not get any pm/uber items as i needed to grind out 5 mil and by that time the item cost 7. i would not like a handfull of players who could build end game loot and ration it out to their buddys.or to the highest bidder, who prolly bought the credits from a 3rd party credit seller. then add the few uber builders spamming channels hawking their goods.
i think this would detract from the simple open community we have now.
just my 2 credits 8)
edit if you feel like paying for an item/service just give the other player a tip. im sure some would take it. 8)
