Any chance of you limiting this to only removing all players on map over 3k? The all players functionality is pretty useless to most people, and probably the laggiest, but being able to see friends and guild members is really useful. My last few days of towering felt really awkward without being able to check the map and see where my guild was.

Then again, I doubt most people used that feature anyway, so if any lag was reduced then it was probably from friends/guilds.
