I've had the same feeling too. The more Sol videos I watch, the less excited I feel about playing AC. However, when I watch Ky and Order Sol videos, my mouth salivates at the potential those characters have. I may even pick up Dizzy again as well!
Things I like about AC Sol:
- Untechable throw
- New GV
- VV back to #R VV
- CL SW easier to hit
Things I dislike about AC Sol:
- BB sucks (follow up combo in the corner is rather lack-luster)
- Fast-Break Fafnir seems worthless (OS's seems much better in comparison)
- 0 recovery on j.H gone
- VV back to #R VV (less damage )
Overall, it seems like characters all got something new and fresh to play with... but Sol seems like the same old Sol we've been playing since XX minus the DL. I was hoping for cool, new stuff that made Sol exciting again... but there's nothing at the moment. It's still early in the game, so it's difficult to say how much potential Sol has in this version of GGXX. However, regardless if he's still good or not (I'm sure he'll still be a very solid character), I don't see him being that exciting to play.
