Massive Rhoa bug, WTF?

While being mounted on a rhoa your stun buildup can't go down. (You can see your stun meter on the bottom left.) Usually the stun buildup recovers fairly quick around maybe five seconds after getting hit, but when mounted it NEVER goes down until you get knocked off the mount. It's possible to recover stun buildup by just dismounting... and then you have to mount again, resulting in additional micromanagement because of the bugged stun buildup. (Mounting Hotkey when??)
Considering how big of a punishment getting heavy stunned off the rhoa is meant to be, this is a ridiculously big oversight. If GGG doesn't get this fixed by 0.3 I've lost all hope of even giving any feedback anymore
