I've been playing League of Legends casually for just under a year, and a few months back I discovered Arena of Valor, a mobile MOBA from the parent company behind League. I was surprised by how well they translated the MOBA experience into a quick but satisfying mobile format. After playing quite a bit of AoV, I discovered a new mobile MOBA, Onmyoji Arena, last month. It has a very cool and cohesive Japanese art style and the character design seems creative and smart. I'm extremely impressed and it has pretty much replaced AoV since finding it.
There are a few other big mobile MOBAs out there - Vainglory, Mobile Legends - but I haven't played any others. Anyone else play these games, especially Arena of Valor or Onmyoji Arena?
