Short circuit: Change it back to the way it was, add switch speed as a bonus
Wrangler: Shield does not come out instantly (maybe ~second till it comes up), shield only doubles health (as opposed to triple), remove shield immediately when sentry is unwrangled.
Gunslinger: Sentries start out at 0 as opposed to 100, like how a normal sentry is. (edit: regen was patched out already my b) Nerf range so it's shorter than a level 1 (right now it has the same range as a level 3 which is dumb)
Rescue ranger: Cannot heal sentries with a wrangler shield around them.
Bam. Pubs are now like 100x more fun.
