Well, in the context of what @korznik wrote (I assume you were replying to him?), we have and always have had 4 classes. They were going to release additional classes on a regular basis (source).
It’s true that the trees have opened up the ability to take variants of those classes in the way that they made multiple Bardins/Sienna et al. in VT2. But a new class in itself would still be nice. I didn’t like my second zealot very much anyway, so happy to nuke him!
