What is the strangest, most unconventional strategy you have used or seen while playing TF2?

I personally enjoy playing medic and using the crusader’s crossbow to snipe people from the battlements as opposed to just playing regular sniper. You get a full field of view, fast reload times, and visible projectiles which makes adjusting your aim easier.

Plus since it heals your teammates you have double the targets available to shoot, and when combined with the extra challenge it make this dumbass playstyle pretty fun.
