>>49532949>fix unovaBW & B2W2 enjoyer here, all they have to improve in BW is adding gen 9 QoL, balance the EXP gain to account for EXP share, add all pokemon up to gen 9 in post game and update the graphics and soundtrack.
Now if they want to actually expand on BW they should:
add side quests and minigames alla HGSS
make some post game stories where you play as characters from Unova Link to set up for the B2W2 remake, which they hoopefully make in the generation after BW.
