that may be true to some extent at first, but all who participate will get a share of those credits spent thereby making them better equipt to win an auction next time.
in live we had nearly 200 players at these raids and most items went for 20- 50 mil. so the credits recieved by each player wasn't as much as it would be here.
in these emu raids i've never seen more than 5 groups of people, thats only 30 players. if you have 5 drops go for 40 mil each thats 200 mil devided by 30 players = over 6.5 mil per player. and drops that didn't get auctioned off would still be lotto'd.
also many players already have multiples of some of the more coveted drops, and i don't think they would bid 100's of millions or more to win another copy, just to keep someone else from having one. but if they did thats alot more credits for the rest of us.
if i have a choice of doing a raid, with a 1 in 30 chance of winning the lotto on the one item i really need or want, as opposed to at least gaining more credits to someday be able to win the item, i'll choose the latter everytime.
