I feel like the game locks you out of other areas for too long (GDC)

[7ravens]

Pretty much the title. Once you get to chapter 9 and go to GDC you are no longer able to go back to any of the other regions (gearen,sheridan,terajuma etc) until the start of chapter 13. 4 chapters might not sound like a lot but the later chapters are significantly longer than the earlier chapters. I think chapters 9-12 isn't too far off in length from all of chapters 1-8 honestly. So once you you start chapter 9 your no longer able to use any of ev training rooms (although i guess you can still ev train with the power items), buy anything from lost camp, do any sidequest you may not have finished (or may not have been strong enough at the time to finish, things like rift chandelure can be pretty hard), or catch any pokemon from any of the regions of chapters 1-8 (I think this is the big one, since there are lots of extremely tough battles in chapters 9-12. If you find that your team is lacking or you need a specefic pokemon for a strategy, you can't get them). There's even a guy with a boat in GDC that offers to take you back to east gearen, except he can't because his boats always full until you get the fly tm, at which point you don't need him anymore. Yes the game does tell you to take care of everything before leaving for GDC, but for example you may need a mon for a specific strategy to beat a boss fight and you didn't know you needed that mon until you got to that fight. Or if your just human and realize you forgot to to do something and realize later that you really wanted to do it. It just doesn't feel necessary for the player to get locked out of going back to other regions for so long.

Yea they really should let you go to to the main island around the late 10th chapter also you cant just be like yea imma just finish the side quests after the main story cause 2 of the main quests dissapear if you got to gdc without completing them novae's quest and the hidden library especially the latter cause you cant get many crests or lo. Also  9-12 chapters are the hardest and most time consuming chapters so far

so is there any new sidequest in v13

Also, by the time you get to Fly to East Gearen City, the city would have already been remodeled, thus rendering the older sidequests replaced by newer ones.
