No one sane will take them anymore, anyway. You can't top the scoreboard relaying only on crossbow, they take forever to reload, if you manage to hit anyone in medium armor that just pisses them off, and there is no way you can reload before you get engaged in melee. Best case scenario, you get to fire three bolts with an arbalest per round. And sure as hell, you will not one shot anyone, unless you hit headshot, they are naked or already badly injured. And that's it.
Just try to count the number of dedicated crossbows on servers, and you will understand just how nerfed this weapon already is.
And if people are STILL not happy, just delete crossbows from the game.
