Stay in your lane
After playing many games, I find staying in my lane and taking towers wins games far more than when I group up with the rest of my team to fight.
Let me know if you disagree, but after playing maaaany many games I've noticed that focusing on your lane wins more games than roaming from it to gank other lanes. When my laner leaves to go gank, I take that opportunity to either kick in my lanes tower or get it fairly low, giving us a higher advantage. People always get mad at me when, instead of staying in mid lane with the rest of my team, I run bot or top to kick the tower in and leave. But note that I don't leave in the middle of a fight, I just see that both teams are playing passively, so instead of sitting behind our tower waiting for something to happen, I take advantage of the enemies grouping and put pressure in other lanes. Even when it's MY lane that's being ganked by a bunch of people I try to get my other teammates to take their lanes tower, but they always want to run to my lane and start a fight. a tower for a tower is better than a tower for a kill or two, in my opinion. I just find it stressful when I see an empty lane with a free tower to take and my teammates are "grouping up" because they want to start a bunch of team fights. But please educate me if you believe grouping is a better tactic than pushing lanes.
main, I agree. Issue is, most the teams i get lose all sense of logic lategame, and make poor teamfight plays. So I just pressure the enemy towers.
and split push your dream out
main I disagree. We all should mid in start, so we can gank. all mid in start = gg
