Ok so I have an idea regarding the EXP and my idea is that it is on the hud along side everything else that is currently there and regarding the plaza it will have that but also depending where you are at You could have two EXP bars cause not Only you are in the plaza but you can have second one besides or above the EXP bar for the plaza and the second EXP bar would vary area to area for example you are in the plaza you will only have one EXP bar but if you go to the minigames it will show both a plaza EXP bar and minigames EXP bar and this could go on for pretty much every other plaza activity
