Stairfights make many fights problematic and repetitive

I've noted that many locations on the server have a stair followed by an open room, and that the mobs spawn as soon as someone reaches or crosses the last step.   Considering that most stairs are transitions, this means that party members entering the room walk down, spawn the mobs, and are under attack before the entire party walks through.   This also means that the hapless individual who crossed that threshold is usually cut of and surrounded, while everyone else is crammed into a tiny rectangle unable to escape off either the sides or front and thereby wasting the large portion of the room.

I have observed this to occur in various locations, such as the Diver, the Dojo Masters, the first room in the Desert Barrows.  To some degree, the Factory has this, but it is at least mitigated by the door, which can be opened when the entire party is through the transition and ready.

I'm not entirely certain the best way to address it, but it seems like having bosses remain neutral or at least unaware of the party until a clear threshold is reached: either by pre-boss space as with Shelob and Twins, or by use of PC triggers as with Quelzarn would to a good way towards reducing stair-trap, as would having spawn- or aggression-triggers not directly at the base of zone transitions.

I'm reasonably certain that there are more examples, but those three have certainly causes their share of grief when effectively every fight is conducted in the exact same tile of a large room due to spawns mobbing the party at zone-in.
