after having seen how bad this can get myself with svara & odin, i feel like it's not enough to only point a problem out and describe it.
so here you go, watch this video and you'll understand how bad things can get.

i agree with ryuko, the priority in which pcs, npcs, monsters, and party members/fc/ls members are displayed needs to be changed.
or simply increase the maximum number but display any player above the limit in minimal details, like a simple black hooded robe etc.
