Are Shapeshifters to strong now?

I played a 100 life win in TFT ranked today at plat 3 rank. First time ever! so really happy, but I also think shapeshifter are a bit to much now. I lucked very much and opened with a nidalee with rapid firecannon and red right off the start and got some other lucky moments in the game aswell. I wrote my progression down under the post, what do you guys think, are shifters to strong? or was I just immensely lucky?

Progression: (only when team the composition is noted, which is about half of the fights):
