i would say this has nothing to do with mutiboxing, master loot was changed for a few reasons and in the normal world they had no choice using the new tag system. in fact we get more loot!

as for FFA in dungons i did not have problems on ptr or beta setting it with /ffa so it might be a bug.

fiddler's loot-a-rang is a very cheep item its a little unfair anyone can have it when engi you don't normally make a lot of gold from. but the engi toys are fun!

and 200 in engi is easy to get, if your a miner even easier.
