To tell the truth,I dont think the coins will kill the server,even they got +16 TOP B weapon,so what?the price of +16weapon is about 4bi-5bi.its not very difficult for players if they insist to play.its already so many +16 top B weapon in server,it wont break the balance of the server,the amount of coins is 400 or 4000,wont change anyting.
no matter what new system add in server,it will help old players much more than new players.for example the new quest of bounty hunting,it will help new players to get some scrolls to sell for adena.but old players will use lv61 characters to hunt in ancient battleground and finish all characters' quest in 1-2hours.if your character is lv61,just need to hunt 200 monsters to get 5 supply boxes.I think new player will finish about 2-5characters' quest one day,but some old plays can finish about 40-50 characters' quest everyday.The only value of these level 61 characters is to get enchant supply boxes.
so many enchant scrolls,few weapons,its strange.the Asian plyers who love farming get much more than new players from this new system.I think the amount of supply boxes that lv61-75 characters can get from daily quest need to adjust.
by the way,the raid bosses became a tool of farmers to get coins and endless lv61+ characters now,without competion.
