I think that this is quite universal for all of the different legends but some of the animations can be a little long and can sometimes really adverse your experience with the legends, hopefully if you gave all of the legends the same treatment then it would balance it out.

For me even though I don't particularly main any one character I find that the character animations for some characters can often feel sluggish and out of place in a fast paced shooter, hopefully these tweaks would make the game feel a little more zippy and wouldn't adversely swing the balance in any one characters way.
Even though I agree with you that these changes happen, it would be ANNOYING AF when you're in a fight and 3/4 different teams pop up (considering you've been there from the start), you'd have no time to rotate or leave the area, since the current bombardment times and delays for everything allow you to only just escape the area, also, i think the devs have had delays on ultimates/tacticals so they don't become overpowered, but there is still ways around activating things. E.G activating bloodhounds ultimate on a zipline, its instant.
Ultimate's speed should stay the same, but tactical speed for some characters do need adjusting. for example wraith, it takes a good 2-3 seconds to activate, and half the time you've got enough time to turn around and look at the enemy for another second before you're just about to phase and you get shot.
