The ult cooldown of the footknight seems to randomly go down a lot faster than it should/even jump down immediately after using it. The Video shows two following instances of this bug. No talent/trait was used that affects cooldown in any way. I was able to fully use my ult 3 times in under 30 seconds.
This appears to be a bug, right? I witnessed this in a lot of my games in the last month and now could capture it finally. This happens regularly therefor, but I am not sure if it is a beta bug or on live as well.
