Alot better than this constant aura and area sh*ts which make some players constantly drop again and again and again. They even make special chars for bosses.
Make things random. Problem solved.
Any contribution logic which gives better chance can be exploited. And it is widely exploited.
You know how many times i dropped at bosses in normal setup for 2 years? 2 times at evendim and it was because i was constantly on tank. Then everyone started to do it. Vesper nada. Not that i care. Both drops given.
Random will solve part of the boss wh*re problem. If not all of it. Drop boosters must be excluded from bosses too.
