Myself aswell many other players have noticed that the Donation Mwall has a bit of a length timer (40 seconds). I propose that it be shortened to 20 seconds, like the regular mwall. However, the exhaust will still be very fast like the current mwall.
Here is an example of the donation mwall at play.
