In my opinion, the Dragon's Fury is a little unfair to fight against. Just 15 minutes before writing this I went on a Rampage and got a few kills I didn't deserve. The main problem with the weapon is that it's firing speed is a little to fast. TF2's fury had a good firing speed with it being not fast, But the TC2's fury is a little to fast. It can shred a Brute in a matter of seconds. I can confirm this because I've seen it on both sides, because when I used it I absolutely destroyed a Brute and before that when I was playing Brute with full 300HP and faced up with a Dragon's fury arsonist I got destroyed in 6 seconds max. also the push force is a little annoying to fight against.
So basically there are 2 things to fix
Make the firing speed slower [Possibly the same firing speed as the Stock rocket launcher]
Maybe nerf the push force I dunno ROLVe doesn't have to but it would be nice if they did
