As a high elo player, prioritizing ganks on winning lane is not something I would suggest
Constantly on the boards I see this notion that a jungler / midlaner should only be ganking winning lane
Here are reasons why I dont suggest this
- Killing 0,3 enemy really doesnt do a whole lot
- bounties
- People ARE psychopaths
Now there are some exceptions atm if you have Kaisa in your team ignore every other lane gank where she is
I heard so many times from jungler I cant gank for you because he ll kill us both (yet he can barely even kill me/x person) honestly if toplaner / midlaner can 1vs2 you are in low elo up against smurf typically
I am always looking to carry a game and most efficient way of doing that in my book is by being better then the best enemy carry player and trying to de-accelerate that enemy. even if you identify that someone has no idea what he is doing getting fed of him and getting him behind doesnt do a whole fking lot since chances us this person wouldnt know how to carry / play when ahead anyway.
