Addendum regarding Failsafe:
I think it could also use a future rework to something like this: Upon reaching 30% of your maximum health or lower, reset the cooldown of Rocket Boots. Internal CD- (55)- (5/5) seconds.
This would make people consider more if they want a few seconds off of Failsafe CD (rank 5 is IDENTICAL to rank 3 on live), or to invest it in another card. It's an overall nerf that makes it so you don't always have to run Failsafe rank 3 (or maybe rank 2 is OKAY as he is on live with 4750 max health, as 20% of that is still 950), and Failsafe past 3 is a complete waste.
