Why is his element countering his own kit?

Is he supposed to be played against non-imaginary sides? I don’t intend to pull for Tribbie, so I only have RM/JQ as dual DPS buffers (if he’s supposed to run with Castorice). But imprison on top of RM’s ult? Is there some part of his kit that I am missing that suggests he does want to break for some kind of benefit?
