Wat Tambor Tech Question

Tambor Wat will be showing up soon in new TB. I know we haven’t been able to test anything but I wanted to get some idea on this key thing.

Who does Wat prioritize his Tech to? Is it based on stats (like Chewie guard with weakest ally) or is is based off of class (support, tank, etc) or is it random?

This would help the community to know the different ways he can be used on defense. Thanks!!!
