Demoman Vs Medic:

1. Introduction
Medics have the amazingly powerful supernail gun and those annoying concs. And they can infect you too. So don't let the doc ruin your fun.

2. Strategy
Watch out for concs. A good medic will probably try to conc you. A conced demoman is pretty useless, except for randomly throwing pipes and grenades. You move at the same speed as the medic, so if he tries to run past you, you can pursue him and shoot pipes in the back.
