Okay okay I know this is rather a lot to read but I pictured this would be WAY shorter in my head
There should be channels for global chat for actually talking to other players and not just for recruiting players. For example earlier I was surprised to actually go on global and have a nice conversation with some players there may have been a few players recruiting but they weren't spam/flood chat with recruiting. That's why there should be separate channels such as Ch.1-5 for either different countries or just in general different channels for people to talk to other people outside their team. If your team if offline and you have questions no one's going to answer until someone comes online but if you go into global sure there's a chance someone's gonna talk to you but with the constant spam/flood of team recruiting it'll be rather difficult to get an answer. As for recruiting there could be a recruiting channel say for example Re-Ch1-5 so people who want to recruit go there and recruit players and if they try and spam/flood the global chat channels they either get forced into the recruiting channels or they get a minor warming for spam/flooding global channels with recruiting.
