It can definitely do that in the next 5 if Riot continues to change the meta from time to time and add new things such as map pools, agent pools etc. I would love to see those things in the coming years
riot's actually doing a great job managing both casual side of the game and its esports. definitely only going to grow despite it being kind of huge already
They will keep adding agents until they run out of colors to make the flashes. Get ready to see white, black, red, yellow, pink, grey, and brown flashes within the next 5 years
Honestly i think they need to slow down agent releases because i think they wanted a new agent every 3-4months and imo 2 agents in a year is already overwhelming
