The disrespect saying dota is a knock off of lol
Dota came before lol and is way harder.
Riot dumbs games down for casuals after copying them. They did the same thing they did to dota, as they did to CSGO. Copied the games, modified things to make it popular for casuals.
So no lol is most definitely not a knock off of lol. Cs isnt the first valve game riot copied from
