GA and Redemption would pop too early on Shyvana when she was transformed

I had GA and Redemption on Shyvana. I also had 3 shapeshifters (which causes shapeshifters to gain bonus HP when they transform). This combination caused Shyvana to pop her Redemption and GA when she still had quite a bit of life left (roughly 40% left). She was nowhere near death, for most of the battles, but every fight that she got down to around 40%, she would pop both.

I'm guessing that Redemption and GA pop when she hits 0 base health, not total health. That is, those items aren't factoring in the added health from her transformation.

I'm a little sad because my two star Shyvana was super strong. With 4 wild, she did some insane damage. But she kept getting shut down long before she should have. Oh well, I get that TFT is still new and bug ridden.
