If Mike Mearls said the sun is purple you'd believe him. And of XGTE was 60% table I would have gone no where near it.
Honestly I've been extremely, extremely patient with WotC, but honestly I've had enough of subpare products that glimmer with potential that is unrealized.
Until WotC gets it's act together, I'm done, I give up on the hope that they will organize and focus their books properly. If they do some something right and put out a quality focused book, I'll buy it, but till then I'm with books that don't know what they want to be.
And a lot young players don't know any better because they've only know 5e, they don't know how book used to be organized. Not ever book coming out should feel like a compilation of borderline random Dragon Magazine articles.
