/who request limits for /who all guild
 

IIRC on live if you were in a guild and did; /who all guild it would not cap at 20 members it would retrieve the entire list as if you were doing /who

Anyone else remember this? Also you could not check others guild it would cap at 20, but for your own it would have no limit.

This is true to an extent /who all guild would indeed cap, BUT /who all GUILD would not, dont understand the case sensative but thats how I remember it working.

No. Both /who all guild and /who all GUILD capped at 20 members. /who guild (in the same zone as you) did not have cap, just like /who doesn't have a cap.
