what do u think about riot adding new agents every season? do u want them to stop at a certain number? i think they should stop at 25-30... but u know.. they want to make money
the more agents, the more diverse the cast and thus more interesting the meta. creativity in team comps will only get better as more characters are added due to team's playstyles are catered towards with the wider range of agent picks possible. as long as most characters remain in a fairly balanced state they shouldn't stop adding agents any time soon.
id like them to stop once they have enough agents to comfortably implement a pick/ban system. It doesnt need to be too bloated with hundreds of agents, but 50-60 would probably suffice to allow their to be a healthy spread in the meta and still have go to agents, along with being able to have a ban system.
