I.E is it nigh time for Evasion to have a small CEL-based chance to completely negate damage?

no. this just compounds the problem of evasion being % chance to not die with heavier stat investment than tanks. completely negating damage is way way stronger than negating a portion of damage dealt, there's no way to implement a universal dodge wtihout it being too low of a chance to actually rely on or too high of a chance that battles become even more RNG/Math based rather than actual tactical decision making. cobra works in part because everyone (should) understand the circumstances in which it works and in which it won't and are able to play around it accordingly.

if an evasion overhaul is going to be successful, imo, it needs a way for both players to actively interact with it each turn. there should be ways for evasion characters to actively work around their opponents moves and a way for their aggressor to limit their options/have meaningful counterplay. 

other than 'just give everyone cobra lol' the first thing that comes to mind is some kind of 'posture' / 'flow' system whereby characters are encouraged to make precise, thoughtful moves that conserve their momentum/movement tiles in order to focus more on dodging incoming attacks, and disruptive/disorientating techniques can be used to 'throw them off balance' as it were.
