Well, we had an old system where people could do the same - check 10 easy spots and delete if unlucky - but noone did. We have a new system where people bitch now, so this wont be WORSE in this certain point.

Also you can set different chance for different spots so easy spots will have a bit less chance to give sleek than a 'hard' spots.

For me this looks like certainly better system than current: it forces to explore but it gives pretty good chance that you get your precious even if you dont know all 60 locations.
