Think about the word handicap and what it means, now think about what you are advocating for. It makes no sense to condemn a player to little to no chance of winning for joining late. People who abuse it are punished when caught, pretty simple. If you see someone doing it and an admin isn't around or noticing it. Report it. The handicap is perfect where it is now.

Edit: if it still dosnt make sense, think of it this way. How is putting someone on scout while the rest of the server is running around with tmps and pistols a BENIFIT to that player?
