Thanks. I ahve to agree, most of his costs/numbers were calculated with a high mana-pool in mind. I think I will add the flat heal to E, as I already considered to do so.

I compared his ult to a few others, but totally forgot about Lulu, whose ult would be a more fitting comparison. Thanks for that hint.

I checked Lulu's numbers and you're right: she grants greater numbers for a greater duration (unless you get ~ 4000 mana, then you can activate Baeny's shield for about 8 seconds).
