Heavy Responsability

My biggest flaw in Team Fortress 2 is... I am very bad at using the Sticky Bomb Launcher. I do very well with the Grenade Launcher and can MVP with demoman with just it but all goes south if I swap the shield for the bombs.

I'm so bad at demo I managed to learn how to destroy most sentries as a Heavy, which sometimes involve doing huge detours or exploiting sentries line of sight. If all fails I swap to Direct Hit soldier, kill the sentry and go back to Heavy.

So yesterday I decided to practice just a bit, using a vanilla loadout and of course a medic come from nowhere with a full uber and before I can say anything I'm invunerable and with only a marginal idea of what I should do.

Good thing demo is OP and we won anyway.
