FF has it's own share of issues regarding dangers of what people can cause if they don't read or have any other sense than hurr durr enemy hurr durr shoot hurr durr durr without overloading their brains.
But when you see a demoman who is aware how FF works and how to play with FF, it's quite amusing.
I'll be interested in seeing that for sure!
Maybe I just have a bad first impression about demoman in FF server because I played with one who wasn't so bad with it but he made some mistakes where, I guess with some thinking, you wouldn't have thought right off the bat that it would hurt your team.
I mean, he did everything right, from shooting the entrance when we were holeing up rooms to not even firing when I went near an ally who was near an enemy and healing him.
But some things happen that is out of control. Like one time this crawler suddenly appeared infront of him (from the ceiling, cursed crawlers) as soon as he pulled the trigger and BOOM! Damage himself, but what he didn't count was that not only he was damage by his own launch, but also the rest of us who were near him suffered damage as well.
Another scenario, was when I was following him in the Biotics Lab. He turned right into the corridor but what I didn't notice that opposite of where he went was a huge mob of monsters opposite direction of corridor he went to, so me, who was following him from a distance, as soon as I go past the door and entered the corridor, I was met with splatters of blood and smoke with my own character trying for someone to do something.
Maybe if the guy was terrible, I would have just dismissed it but he was pretty decent. I guess when it comes to FF, there are some things people do, no matter how careful they place their shots or aware, that situations like I name above can hurt your teammates unintentionally.
