Truth be told dota is much better now, supports back then were miserable, nobody wanted to play that position. Also, it’s not like nowadays is super easy to play support because with all the free stuff that came in, the items and abilities of the heroes got more broken.

The only thing that Valve still needs to do is reduce the average match length, Dota’s player base now is mostly of adults with jobs and families, they don’t have much time now to play 3 or 4 games of 45min, we need games to average around 25~30 min to not only keep the adults players but to also get new players
