Really great ideas by Triad. If match making become a reality I would play more leagues. In League of Legends I played ranked games a lot, many hours per day (I rarely played for fun, I used to play like more than 10 solo queue games per day). In WA I really don't have much patience to play ranked games. The very good part of WA for me is the creativity it brings. In League of Legends there is not much creative things you can do. You can make fan art, but that will not be inside the game. You can play with champions with bizarre builds or bizarre roles but nothing too creative that you can see inside the game as WA.
Many league players were not very cool to me too and many were very against new schemes they only thought about leagues and nothing more. If you don't play leagues you are noob, if you edit one thing in the TUS scheme, you are noob. And that made me avoid playing TUS leagues. I know many players who don't like TUS so much due to this kind of behavior of the players. However with time I started to enjoy TUS and see other aspects of the site such as a very good platform for schemes with the best actual editor (better than the game editor AND SchemeEddy), it is the only site I know which has scheme icons, this is really a great feature, the website is beautiful and well organized, I like the communities, the maps don't receive bullying tags like WMDB "UNIMAGINATIVE" (this is the worst tag and useless of all), etc, etc.
I believe with new updates coming people will start playing WA again. Like many people I see are playing again. Now with the custom terrains it is more fun to play in random maps.
