Help needed for levelling

Mackeral313

I've not completed act 6 yet I'm on 6.3.2. i feel I've been generally lucky with my champion rolls by this stage but struggling knowing which ones I should be focusing on levelling in order to clear act 6 and beyond so any tips would be massively appreciated.

I have 5*s like awakened human torch and an unawakened warlock I'm also considering levelling more but unsure if it's worth it considering the 6* pool I now have. I also have enough dust to ascend 2 5 stars and a 6 star if I should but considering only 2 are awakened do I just wait.
