There's a reason why this happens. and it's down to the loot system itself. you can obtain 1 item in a week, and this week for example I want the shaft from a12
if I roll on the shaft straight away. i'm probably rolling against 7 other people to win it. gives me what a 12.5% chance of winning the item.
if I wait however till the cranks and springs have been won. now there's only 4 people that can roll against me for the shaft I want. so my chance of winning now goes up to 20% maybe less if everyone has passed one of the drops.
so generally speaking i'm not going to roll on that shaft until the other 3 items have been won because waiting improves my chances just that little bit and i'd rather wait a couple of minutes than have to run the fight for a "n"th time that week.
what makes it worse though is my mate over there only wants the crank form a12 this week, and like me he won't roll on the crank till the rest of the stuff has been won in order to maximise his chances of winning.
and now we're at a stale mate. cos I wont roll the shaft till the crank has been won, and he wont roll the crank till the shaft has been won and perhaps some other guy won't roll the spring until the crank and shaft have been won and thus are we all stuck there waiting till the last second.
as a result I tend not to mind it so much because I know and understand exactly why people do it. to increase the chances of winning the item they want that week.
why not just let people need roll on ONE item. regardless of drops. if 2 shafts drop you can only roll on one. and you can't roll anything else from that fight regardless of whether you win or lose with that one roll...
that way people would roll faster. and loot would be won faster. but as long as people can roll on everything. then people will wait till the other stuff is won.
