Ah thanks!
I've been doing arcade mode on normal, trying to find a character that I like, so far I like using Dudley, Cammy, Evil Ryu and Juri. I think I just have to get used to the move timings and work on my blocking! When I went online it seemed like everyone I faced where able to read 99% of my moves and block accordantly.
Also, I swear some of the player trails are near on impossible to do.....
