The range of the Zeus x27 is extremely short, you practically have to be within knifing distance to use it. In real life, stun guns, especially military stun guns, have a much longer range than two-feet. Would you want Valve to increase the range of the Zeus x27?

I never see anyone using it, it does seem a little pointless to be honest, but then there's already one long-range one hit kill weapon, the last thing we need is a mid-range one.

Nah. That would take the fun out of it. It's always fun to tell someone they are going to get zapped and then do it and get a brief round of server applause.
