The one spot I see people die often in that place, is the first boss.

Honestly, I've seen more struggles with giant pulls when people forget they're synched down to i440 than with the actual bosses in there. (Though I have seen a breathtaking number of people accidentally dash/dive/backflip off the arena with the final boss.)
