90% of S2 problems come from the fact that they had to cram two full length seasons into a single season. Fucked up pacing, skipped pieces, retarded motives, it's all there. Tencent just realized no one is going to play their shit no matter how good the Arcane is, and pulled the plug.

You want a nice casual dota-clone with interesting and cool heroes? Play HotS.
You want a deep as fuck dota-clone with skill ceiling so high it takes years to get anywhere close to it, plus once again interesting heroes? Play actual Dota.
You want Jinx? Watch Arcane.
You want to eat shit? Once again, the market is so overcrowded, you can't compete even here.
And they're still trying to find their niche to attract more players. With no success so far.
