League of Legends is a STRATEGY GAME
You do not win by "GO BARON NOW, FIGHT, NOW DO THIS NOW GO GO GOGOGGOGOGOGOGOGOGOGO KILLs KILLS KILLS" every 2 seconds.
To many games I've seen lost just because people didn't plan out what they were going to do. Going to do baron? Ok what are you going to do after? Are your waves shoved? Is it even worth it? Wheres the enemy? Do we have enough damage?
I know you don't have voice comms but a simple "Ok guys were going to do X, so we can end up getting X". And not just blinding starting fights because you had an urge to fight.
Example I had a recent game with a Yasuo would just Constantly fight and fight and fight. Without planning anything ahead, sure he would chase someone out for a kill but realize that none of the lanes waves were pushed and we couldn't contest any objectives afterwards. He would start baron without warding around for the enemy team. He would constantly dive an enemy for no reason other then to kill and die trying or end up losing objectives because he didn't see the enemy on the other side of the map.
Point is, don't blindly to shit just because you want kills. League of Legends is a strategy game NOT a fighting game.
