I wanna destroy my friends

Can someone train me or give me some pointers, my friends and I enjoy RoA2 as we do most other platform fighters, and they are really good at it, but for some reason I can’t seem to get to their level; I try to practice on my own or learn by doing by just fighting them but to no avail. I know a good handful of certain techniques ( short hopping, fast falling, teching) but I can’t seem to utilize them properly. Yes I asked them for help me out but they suck at explaining things and they enjoy bullying the weakest link, I can hold my own but I’m always getting dog walked. I NEED HELP, I WANNA DESTROY THEM!
