Karma Shield Design/Balance Question

Or we can call this "How I learned to stop worrying and love the design process"

A month back Scarizard mentioned that he was going to converse with his team about making her Mantra E feel more potent/or better even when level it last.

Some kit suggestions or small changes had been popping in my head and I wonder "Why would not implement___" then I really think about it and say "Well, that's a dumb idea" or "Riot already thought of that and found that it didn't help" but the question is why in a specific case.

I know it probably wouldn't solve the problem because it's closer to her giving her bonus shield on Mantra but here's my proposal anyways;

Why not add a Mantra shield strength value that scales with Mantra level like her other abilities.

Side note: Will we ever see those visual updates/changes Volty said he was working on or is he working on something else now?
