Every time I attempt to split push, or even just clear a huge wave pushing top/bot when my team wants to go mid, my team engages and gets murdered. Today I was even told to uninstall for clearing waves pushing my team's inner turrets, when we didn't even have a clear shot at destroying enemy turrets. Is there any magical way to convince my team not to engage when I'm not there? This happens every single day, and it's really pissing me off.

umm....shen/tf and t/p. other than that good luck.

Sometimes the other team is smart enough to initiate themselves when they see someone missing. Think all you can hope for is your team realizes that you are not there or you play Shen or TF.
