JKR revolves around calling a powerful damage dealer to assist over and over again.
Jedi are still very light on good damage dealers, and two of them are Galactic Republic. Without GMY and Anakin (who is hard locked to Padme), your only viable damage dealing option is Ezra. And even that is barely.
You can leave GMY in your Padme lineup for arena, but for GAC and TW, he should go with JKR. The core power trio is JKR, Jolee, and GMY. The team does not work well otherwise.
Ezra and Hoda slot into the open spot left by GK just fine; JKR teams don't really need a tank, especially if used on offense. Which is generally their better use these days. If you're placing JKR on defense anyways, Ben is... not good, but okay. As is Juhani.
