Although the weakest member in a offensive attack by themselves, their task at hand mirrors the title of the game.

Medics are/were my preferred class soon after my fun with the pyro, based on various reasons, my team would lack a vital healing member.

I had a purpose no one (unless they are idiots) can really complain to a Medic if they are not willing to take up my duties. Besides, it is just a game. Some of us have more important priorities than investing our time and money in video games.
