Maybe I just don't quite understand how Movement speed works in this game, but I'm pretty sure this is a bug.
Base stats, Rumble has a movement speed of 345
With Boots 2, Rumble has a movement speed of 390.
Using his W at rank 5 with boots 2 he now moves to 484
Using his W at rank 5 with boots 2 and with Danger Zone Bonus he now moves at 498
Rank 5 movement speed bonus is 30%
With Danger Zone Bonus it is a 25% increase
30% of 390 = 117
30% of 345 = 103.5
390 + 117 = 507
390 + 104 = 494
345 + 117 = 462
345 + 104 = 449
Now as you can see, none of those numbers are remotely close to 484. Am I doing something wrong here?
Also the Danzer Zone Bonus only increases Rumble's speed from 484 to 498. That is only 14 units. In no way is that a quarter increase from any of the numbers I provided.
Once again. Am I doing something wrong? Do I not understand how movement speed calculations work? I really want someone to clarify this as either me doing the calculations wrong, or this is really a bug.
