I’m familiar with the history, and there’s a reason I only mentioned DotA2 - that was the suggestion I was arguing against. I did not claim that LOL was the genre progenitor, merely the game that had the impact.
This in itself is incomplete.
The Dota that Dota 2 comes from is actually Dota Allstars, which is a Frozen Throne update of the original DOTA for WC3 which in and of itself was in a well established map genre called “AoS-type” maps after Aeon of Strife – the original map in this paradigm for Starcraft 1.
