I'd like to see bosses that summon reinforcements. The reinforcements come from the trash pool. If you skipped a bunch of mobs, the boss will call in all those mobs as reinforcements, making the fight much harder/impossible. If you kill everything or mostly everything, then the boss' reinforcement pool is very low.

If you want to speedrun, expect to lose all that time you saved fighting that boss' reinforcements. If you prepare for the fight and kill most of the mobs, sure it takes awhile, but you save time in the boss room only fighting a few mobs.

BTW, speedruns suck. Got enough of that BS in 1.0.

This is a topic where I'm sorta arrogant. I'm the tank, we go at my pace or you can leave. Usually my pace is faster than normal, but not a speedrun. Really, are people complaining about losing 3 whole minutes in a dungeon run? Really? My Brayflox runs are usually around 12-15 minutes. This is with new people and explaining the fights.
