Well, an easy answer is to not allow people to place wards near spawns, create a rule about it.

claws + wards combing?

i can up the damage of wards by default and disable items on ward damage....

I talked to shaw today about it and i do agree to an extent but i am also looking at other viable options that may work even better then eliminating items that work well with other races and classes. The overall dmg on the ward is great, get two people working together with claws, same effect will happen at spawn. but not as often. any other sugestions to limit the ability from causing rage quits will be welcomed but at this point, limiting item enhancements on wards seems to be the best solution that i can come up with.

You could always make a little mod that makes players immune to wards for x time at the start of a round or prevents their use for x time from start of round.
