Mobility's not that bad but the Special Moves and Combos are a real Head Ache. Still better than Guilty Gear though... Guilty Gear had actual button mashing moves... like literally hit as many buttons as possible type of moves.... that was really frustrating.
Yes, Guilty Gear Xrd is easier to play than BlazBlue, though a thing I find tricky with these air dashers is the sheer number of mechanics that you need to know. A lot harder than SFV IMO (possibly KI, though I need to delve into that game more). Try playing Noel or Ragna. Those characters are fun 'cause they're easy lol.
I did manage to get Further in Ragna's Challenge Series but I hit a Brick Wall halfway through, I think it was a 1Frame Link.... Challenge #5. That's when I decided to Bail.
