Then don't buy their stuff.Sure, they don't need to do anything, and I can make my own stuff, but more we get into that territory, less need there is for me to buy their rules.
(I don't care about this specific issue that much, but in general I have become a bit tired of fixing the work of professionals who expect me to pay for their stuff.)
WotC doesn't care if you... specifically you... buy their stuff. Because they have more than enough other people willing to do so. So they aren't going to cater to you specifically. You of course are free to bemoan that state of affairs... and that pretty much is what almost everyone here on these boards do when they're here-- complain about the stuff WotC is making that the person doesn't like. Personally though... I find discovering solutions to issues to be more worthwhile. Both for my own game... but also (selfishly) more interesting for me to read here on these boards.
I find incessant complaining about WotC with no attempts at actually solving the issues to be tiresome and lame. So I will comment occasionally when I see it... recommending that the person solve their own issue so that they can actually be happy. Or at the very least content. That person can then either try and do so with their game... or what is more likely to happen, quote me and complain back that I'm harshing their ranting buzz.
Which is fair. If someone just wishes to rant, they can. But that doesn't mean they get to rant without response. So if I have to listen to people complaining about issues in their D&D game that are easily solvable, then they have to listen to me tell them that those issues are solvable if they'd just stop wasting their own time.
