Alternative to xp loss to prevent bind rushing

[oldfish]

The minecraft pvp server i play uses this as a way to stop people from stone sword rushing:

If you died 1 time in the last 5 min, root for 10sec.
- If you died 2 times in the last 5 min, root for 30sec.
- If you died 3 times in the last 5 min, root for 1min.
- If you died 4 times in the last 5 min, root for 3min.

It doesnt need to be exactly like this, but you get the picture.

I think XP loss is so bad on a pvp server that we should really think hard about a solution to bind rushing so that we are allowed to practice PVP alot without XP loss.
