I liked the screenies and ideas in this game...
What's weird is, Neo didn't close this since it was revived... And coincidentally you're back :P
WB and good Luck.
Anyway...
1. Why multiple versions?
2. Potion making, different potions or the classic super potions, revives etc? If they're just the whole things, DO NOT.
3. Market membership? The things are too cheap, considering an EV trained Pokemon can be Rare Candied all the way to really high levels... (100 or the limit) Getting that much money is quite easy in the official games...
4. If it's only withdrawing and depositing, why have a bank... Add maybe some interest, a share market... Maybe even thieves so it's actually useful.
