I don't like the WoW stuff. Do you? + General Moon Druid rules feedback

I took a quick peek at some of the Druid stuff in the new WoW book and personally - and in my opinion - I feel like Moon Druid (5.5e) got cheated. 

Why? Because whether you're a Feral Specialist or Guardian Specialist, any time you Wildshape into the Cat or Bear (respectively), your WIS score overrides the STR/DEX Scores for the animal you Wildshape into, get to use your Spell Attack bonus for your Wildshape attack. The form's damage dice upscales as you level up. I am baffled that Moon Druids didn't get this feature at the start of 5.5e because they're a Druid subclass that uses more dangerous animals (CR 1 starting at level 3) and - in my opinion - should mechanically look like it. 

I would understand that the damage dice wouldn't change or scale up, but why couldn't Moon Druids use their Spell Attack bonus for Wild Shape attacks??

Why did they do this to Moon Druids? (Help me understand)

Because when such forms were considered as part of the 5.5 playtest, they replaced ALL options for druids.  People who got decent mileage out of small or odd forms hated it.  Introducing the WoW stuff (which is directly out of the online game) is likely more popular because it is an addition rather than a replacement.

There were a lot of good ideas that got dropped in the playtest because they either went too far or had very bad execution.  

From what I have seen of the WoW stuff, some is pretty good, some is pretty bad, and much is somewhere in between.  The sweet spot is good enough for people to want to play but not the obviously "best" option.
