Ya I need to brush up on my TF2 skills.
It's worth noting however, this bitch just killed me the same way 3 times. Has not the skillz to try something new. har har
-You can turn around between every wrench swing so no spy could every feasibly sneak up on you to stab n' sap.
-If a spy saps something, wrench him to the face before saving your stuff. A lvl3 sentry will last 9 whole seconds before a sapper destroys it and the spy can reapply them faster than you can remove them and kill the sentry.
-You can put your dispenser in a corner, then stand on it and whack your sentry, meaning that the spy can't get behind you anyway.
-It's possible to build a sentry far enough away from your dispenser that you can just BARELY reach it with the wrench. This means you're less likely to be hit by explosive shots hitting your sentry and that spies who try to stab n' sap will wind up dying unless they get lucky and circle-strafe in the right direction.
