As someone who never liked league, I always noticed the effort Riot puts into there business. I was a CS gamer even though I quit playing b4 Project A was even announced. When I heard riot was making a tac fps I was instantly hype because they have the assets and capital to bring a streamlined finished project.
Basically, riot has the competitive scene on lock and they can't be stopped bc they have infinite money glitch from league. But they aren't complacent and that's y I fuck with riot. Constant updates, community reception, events that have a level of effort put into them. Also, the anti-cheat needs to have it's own day on the calendar. (I loved CS but had to stop playing bc of cheaters).
TLDR: Bc riot is stacked with cash, manpower, and resources.
