I think Advancing Flow should proc on Evasion like Flottement does, and 'teleport' (Rank) tiles towards the attacker, instead of just 'one tile and walk'. And maybe have a new 'rank 3' interaction that if you dodge/evade in melee to your attacker, you warp to the tile on their back.

Aside giving them what they lack the most, which is a way to stick to the target they're fighting without bigger issues, it will sure make them more flashy and sneaky, when they're constantly moving upon dodging attacks and seeking targets to buttstab. It might also give them a pretty notable weakness, for this new interaction being able to be used to move them away from a position you want, in teamfights or even in PvE sometimes.
