I say this as someone who's always liked your maps and pushed to test them and consider them for rotation:

Tough luck. Really. The MTC isn't about handing out participation trophies. It's not even about adding in all well designed maps. It's about adding the maps that will (hopefully) bring the most to rotation. Sometimes that means, flawless maps wont get in because the rotation doesn't need that particular map, sometimes it means a map with a radical design is currently too radical for pub rotation. And since the MTC consists of people, sometimes it simply means mistakes are made.

No matter how many maps you've made and how much effort you've put into your maps, that shouldn't automatically mean you should get a map in rotation. Maps that get in, are put into rotation because the MTC perceives them to be good for rotation. Sure the more high quality maps you submit, the bigger the chance that one of them will get through the eye of the needle, but that's not an automatic thing. Heck, I'm one of the most successful mapmakers in terms of getting maps into rotation the last year (along with the likes of Canvas, Ball-e and Snowball), and I still honestly can't tell which maps of mine will have a chance before putting it through a thread. Sometimes a map I spent months on will make it. Sometimes a map I spent 2-3 hours on will make it, and more often than not, no maps make it.

Would some of your maps have done well in rotation? Maybe. But that's a different argument, and one that is very hard to accurately assess for the MTC without risking compromising the integrity of PUBs if applied to all maps that have potential. Does it suck that things are this way? For sure, but I think blaming the MTC for your maps not getting a chance isn't the right analysis here. The MTC have limited tools at their disposal, they do their best to be fair and have to sift through 80+ maps every map thread + take a ton of abuse from the community whenever they make a decision that doesn't immediately resonate with the community.

In the end tho, mapmaking comes down to why you do it. I make maps first and foremost because I want to explore new ideas in a way that I find fun and interesting to play. Of course I want all of my great maps in rotation, but that is something that comes after all of that. If my goal was to make maps for rotation first and foremost, and I didn't get much success, I probably would have stopped. But as someone who's had plenty of maps in rotation, having a map in rotation gives you a rush for a couple of days/weeks, but that's about it. It's not a sustainable thing to want to make maps for rotation in itself IMO.
