Teaching laners how to engage for good ganks
So with the triple JG nerfs (camp exp, camp gold and duo lane exp which is less exp while ganking also) the engages are way more important if we want to have a successful gank. Even with solo lanes being out of control op right now we can still gank a solo lane as long as they don't have 3-5 kills the JG can come in and you can both kill the solo laner. With Jg being nerfed into the ground he will die solo to the solo laner and if the solo laner has 3-5 kills then you both will die during the gank usually.
The trick is to engage at the right time; to often when I ping that I am coming for a gank the laner either back as soon as I engage = me dead or engages 10 seconds before I go in and dies as I engage leaving me to fight 1v1 and I die also or goes in before I get there and dies forcing me to leave because I will die solo to the op solo laners which cost me ALOT in the game because i could of been farming or ganking another lane. With no catch up exp a single mistake puts the JG very far behind the rest of the game.
This also is important for duel lanes watching where your jg is if he is pinging while he is coming it gives you plenty of time to prepare and stay alive while he is on the way. Make sure as he comes in you are in position to engage the same time he does.
This will help you win more games because the ganks are more for you than the JG because you get free waves and a lead of your enemy laners which can lead to you snowballing and winning the game. If the engages are horrible its best for the jg to just farm and counter jg/counter gank.
EDIT: I forgot to add the laner engaging before you get there and scaring the enemy off as well...
