The problem is, written text as a tutorial is like worst and most boring way to teach anything in game design. This is interactive medium. We have story which everyone is going through anyway. It could (and should) teach basics of comp play.
Right now it's medium difficulty pve experience. Quite easy for good players, and too hard for ppl who used to beat region with charizard. It's more like test rather than learning experience.
I know there is little space in story to insert tutorial bits but this is the main issue in my opinion.
