Arena of Valor is superior to LOL/Dota2
to be honest i never heard of it, so it may be superior, but it as no recognition yet and if it can't run on your grandma's toaster it will never be as popular, because that is also part of why LoL, Dota2 and CS are still extremely popular e-sport, those games can run on anything, and publisher only now seem to start to catch on to that, most very popular games are either older or are extremely optimized and low-ish graphics. most new MOBAs did not understand that and failed while being technically superior, if only 10% of the playerbase can migrate maybe 1% will and you will never see much success.
