How would this be Heavy's plan..? He is probably leading the dance, if anything.

This. The TLDR version is that after one sucessful full team rush to break the endless death loop my team mates got themselves into, I actually had to push the bomb the rest of the way by myserlf to the end by myself and almost got killed by the few people on the enemy team who noticed. I got lucky and managed to heat shot them to death but I almost died.

The real icing on the cake? I was playing The Medic. Thanks for nothing, team mates.
