If you could replace the Sentry's Miniguns with any weapon, what would it be?
For me? I'd give my Sentry gun a Sniper rifle and a flamethrower and watch it snipe the enemy team and burn all the spies to death as well, and airblast all grenades and stickybombs/rockets away from it too! Imagine having a sniper duel with one of these, you'd ruin people's lifes and make them ragequit!
Crusader's crossbow would be another interesting choice too, then your sentry gun could heal you and your teammates when you got hurt from a safe distance, and since sentry guns never miss it'd be extremely effective. Plus, it'd still do a good amount of damage!
What would you combine the sentry gun with, if you could replace the miniguns with any item/weapon, or hat? Would you make a sentry gun that shoots buffalo steaks at people and club people to death with candycanes? Maybe you'd like to screw your team over with a sticky jumping sentry that did nothing but jump around, post your combos here!
