TP mage recommendation/opinion for summer hyperburn

Hi yall, title basically is the question. Looking to make a mage as a bossing mule in the summer, and i basically have narrowed my choices to I/L, Lumi, or BaM. I’m aware of KMS changes and m3/4 but just not familiar with them as classes.

For those that main or play this class as a mule, what are your opinions on which one to choose? If there are other mage classes you would recommend feel free to share!
