Movement is still very valuable. Probably, the best form of active defense.
Like these tumble changes w/ their 99% evasion is absolutely asinine as a defensive tool as kiting and active movement both of which cannot be done while holding down block (for tumble) is FAR superior in terms of avoiding attacks than a 1% 1 sec buff, where LAG, server side calcs, and your eyeball all have to align PERFECTLY in a 1 in 1,000,000 chance within a 1 sec window to avoid an attack.
I hate the tumble changes. It's a MASSIVE immersion breaking thing when you tumble a couple times and all of a sudden you can't tumble anymore....? I mean, I can tumble 10 12 times (before I get too dizzy) and seriously out-of-shape.(during my H.S. days it's basically walking).
What they should have done is make tumbling fade away gradually if you do it too many times in a row, meaning after 4~6 tumbles depending upon your tumble skill/thief acrobatic/etc. your tumbles will gradually slow down (if the animation can't be fiddled with then create a % chance depending upon tumble skills etc. where your tumble just won't go off when you block & move.) Or too many tumbles in a row and you get dizzy (stunned) for 2 seconds.
This whole dot thing is just the dumbest idea ever. OMG.
