Because only stupid people go to knife TDMs
Great logic.
this entire argument is stupid:
If you don't like knife tdms, don't go to them.
If you like 'em, stay on them.
If they're "taking" potential people coming to your "original" server, advertise on the forums or RTB. You can't blame them for going to a server they enjoy going on. See: Pecon7s Old Boss Battles, Wizzard's Dogfight, Jorgur's Dogfight, Maxwells Valley TDM
Those servers are from a while ago, but they were usually blamed for taking potential players from "original" servers and were supposed low-quality.
