How would those spawns be handled if it's a TDM server (as I guess we agree a free for all DM would not be fair for all classes), WITHOUT preventing the cav from constantly raping the enemy spawn?
Apart from carefully designing some maps where you have to like jump down from your otherwise inaccessible spawn or something like that I don't see a reasonable option, as spawning next to your teammates is also bad in a few ways.
And funnily enough, the respawns and the map duration on battle mode would need to be changed to have TDM. (Nothe that I don't say battle mode sshould be replaced with TDM. I say it should be split up in TDM and conquest.)
