How to truly dominate solo queue

you mean how to dominWAIT

Jungle / mid <3 and </3 at the same time.

Jungle has the issue of deciding on which of the 3 lanes that are usually losing, bordering on losing, or outright feeding will be the best at not throwing any lead you give them or which will carry you. Not to mention that you get to be the scape goat for everyone. I'm sorry solo laners but if you need a jungler to babysit you for 20 minutes in order to not feed or just go even then you're the problem not the jungler (Even in hard counter matchups there is no excuse to go 0/6/0 by the 12 minute mark. Don't blame anyone else but yourself.. Especially if you just died 3 times in a row and decide to still force trades and keep the minion wave pushed to their tower and have no pink ward out and full charges on your yellow trinket).

Mid has the issue of getting used to the constant 5 man goon squads coming to your lane. If you're bad about keeping up on wards mid is a horrible place to be. Mid also has to be able to judge when a roam is good and be the second most map aware player on your team (Jungler & Mid are the best 2 places for people who don't look at the little thing in the corner of their screen or use the f2 - f5 keys on a regular basis to royally screw your team over).

That first sentence for mid totally didn't come from the Annie game I had earlier today that had a constant Yi + Graves + Varus + Nami presence for the majority of the game. I dunno why but I attract constant 4 or 5 man ganks on mid / bot when I play them.

Usually when I jungle, I run on the mentality that you help "winners win" and let the "losers lose". In that process, you have to sort of hope deep down that the losing lane isn't ultra feed. If so, you just hope you get the other lanes fed.

A thing I notice sometimes that junglers fail at it their desire to take kills. I try to distribute them. It's hard to stop a few people who are fed. It's easy to stop 1 person who is fed.
