Overpowered Mutants!

I'm getting realy mad at how overpowered these mutants are. They need to be updated! How about first level mutants fun as fast as a human with no guns a knife (give people a chance wen running away) and instead of just hitting them when u left click u grab the human and then u left click again and u claw them and they become infected (something cool and different), but right click hit if landed will infect them without having to grab them, and they sholdn't be able to jump as high i mean look at them, they're FAT. While a mutant is grabing someone another human can shoot the mutant, thus saving the person. Antoher thing (not to make mutants less powerfull but just for fun) Titans special ability is that they choose a location and jump to it (they have to charge up to jump to it and can be shot to stop them) and if hitting a person they become infected. If they hit a wall then they stick to the wall because of the spikes coming out of their back. Reply, comment, and put your own sugestions from zero.
