While I like most of the personalities, I find it really awkward that your character dramatically "snaps" into position the instant you stop walking or running. Can there be a few seconds delay, please?
It just feels really rushed and not at all like something that needs to be happening. For instance, with the Telvanni Magister personality on, my character apparently can't wait to stop moving so she can quickly flip her hand up to examine it. Weird. Same with the Brassy Assassin... an uncoordinated leaning to the side and hand on hip the second I stop running. Who does that?!? Same with the Jester, and even more noticeable since she sort of skids to a halt and flings her arms out, presumably to keep from toppling over after regaining her upright stature. You can really notice these if you take a step or two and stop, then do it again. There needs to be a better transition, like maybe just stand still or look around for a few seconds and then have the personality slowly kick in.
This would also help at wayshrines, as I notice occasionally that a wayshrine is difficult to target for a few seconds while the personality is activating.
