You consider it poor treatment, maybe, but that's only to you. Like how a bunch of people got uptight about Fat Mega Man being in SFxT thinking that Capcom was doing it maliciously even though Inafune was in on it the whole time and thought it was great. Just because you believe one thing doesn't make it so. Those Castlevania games that you don't like are (or were, thanks to konami moving to mobile) selling, and they get good reviews as well, so you might be in the minority on this one.
I wish I had sales numbers to find out how well all the DS games did.
I liked the Castlevania games, to be clear. They just didn't have the funding and effort put into them that SotN had. That's kind of what I mean - they might be enjoyable, but you can tell the difference between a rehashed sequel and a fully funded project that the company is investing in. Capcom stopped investing in Megaman, so the fans did, too. /shrug
I liked MMZX, by the way. I thought it was the best Megaman I had played since Megaman 2 (MMX is overrated), except for the voice acting. That voice acting...
I don't think Fat Megaman was malicious, but it was undesirable and, from a fan perspective, trolling. Ditto for MM's poster in Days of Future Past. I'm glad Megaman got the love he has deserved in a fighter for the last 20 years in Smash 4. I no longer really care about him getting into Capcom fighters because I'm confident Capcom can't outdo Sakurai.

lol, ew.
In all seriousness, a Megaman Online would be cool IF you got to design your own starter weapon, and then you have to hunt other players to steal their abilities. Then you customize your Megaman like a mech game with various upgrades a la MMX. Tons of DLC options for unique upgrades would keep it funded. You could even have raids and stuff in a 2D field...I think it would be cool, at least. The only game I would purchase faster is a Pokemon MMO.
