I'm wanting to find some info about pro play (agent selection in this case) and I'm finding it difficult to find up to date info with agent pick rates overall, by map, agent win rate etc. Can a kind soul help me out with some link or websit...

We have different kinds of agents (fire, water, air, earth-based, etc) and maps (underwater, snow, desert, beach, city-based). Props to Riot and Val developers for creating complex stuff like these. What kind of agent and map do you think...
