I know movement speed caps at 200%, but does it have certain breakpoints as well?

I rolled a temper, unfortunately, on my boots instead of the GA movement speed. I do get the cap now (even without the last masterwork upgrade), but I'd like to remove a skill point from a movement speed +4% skill. I would then have 199.9% movement speed. Does it matter?

You probably wouldn't notice a difference between 199.9% and 200%, so yeah if it's worth the gold/mats to you I'd reroll it.

Not rerolling, but do you know of any breakpoints?

Never heard of any movement speed breakpoints
