But the UA ranger wasn't even as strong as the paladin. Or an EK. I really don't see an issue. Their abilities actually DID stuff, rather than just mildly improve the stuff most everyone handwaves away (and would still be better solved by a druid).
Really that's the problem. They're basically just a druid that loses half their spell progression and wildshape to shoot a bow twice a round.
Again, I think that Mearls approach for alternate class features will address these problems. At least that's my initial impression.
