I don't post very much, but I felt that this is rather important.
The Sentinels are now rubbish.
You spend your *Profession* choice for 2 soldiers who have less HP than a Peasant, and are un-upgradable STR 5?
Compare this choice with something like "Royalty". Clearly out of whack.
I suggest making them unnamed (or named) Champions who have 8HP apiece and start with Oak Spears and a Jerkin. That way we can level them and they grow so that they stay marginally useful with new items.
