Time for Rex to become farmable?

Honestly, making Rex farmable makes a lot of sense. With General Kenobi coming out and having the best debuff cleanse there is, Rex doesn't really seem as valuable anymore, and therefore not worth the money to spend to get him. Why spend a bunch of money only to end up using him for 1-2 months before you finally have a solid GK to use in his place?

I definitely see why he should be farmable, and it makes sense to make him farmable now, but I wouldn't expect to see it until people start unlocking GK and he isn't needed as much anymore.
