PSA: If your jungler ganks and you're not very low, engage first.
I did not come to 1v1 your laner(s). I did not come to chase him and take minion aggro. I did not come to waste my time.
Engage him, get him committed, draw out his CC/mobility, distract him from looking at the map, fight him 2v1, and he'll die.
Not every jungler is a Sejuani coming to dash-ult your enemy. It makes everyone's job so much easier if you go in first.
Understandable response:
Really? Because if I see my enemy laner with half health jumping me when I'm full and I'm a full level ahead of them, I'm going the fuck back to my tower because I know something's up. Or you know, just kill him and then take his jungler when they arrive.
Engage doesn't necessarily mean ult him. It means bait him, get in position, make him think you're a free kill.
Think of it this way. If the laner doesn't engage, it's free damage on the enemy. In the fight, and in the chase. If they do engage, it's a kill because (no attention to gank, wasted abilities in fight, 2v1).
And it's MUCH easier for the laner to get in range because, if the enemy is in position to get ganked (pushing, winning lane, etc.), chances are he's trying to get in range anyway, either because he's winning or because he's being a moron very oblivious.
Either way, people get greedy 9/10 times and try to fight back, and even desperately chase/towerdive for the kill when I'm literally right behind them ready to stick it up their ass.
As for getting double killed,_ I'm not going to say it never happens,_ but whenever it does, it's because the enemy was **unexpectedly ** strong. If the enemy was a Zed with an ult and you were half-HP, or a farmed Nasus, or a 15/0 Pantheon by 5 minutes, I'm not going to gank unless I was very confident in the kill (ex. Vi gank for Orianna, both with ults).
If I decide the lane is too strong to be ganked, I'm not going to gank, no matter how much you beg (or talk shit). That dragon contest needs me more than you do. But that's a jungler PSA for another day. For today, when you see the green ping and a jungler about to enter the warded zone, GO IN.
EDIT: Okay, people can have bad judgement, even those with a generally good one. A jungler CAN ask you to go into the 500-stacks-by-20-mins Nasus. At the end of the day, do use your judgement. Don't blindly follow other players, especially at lower Elos. All I'm saying is, if it isn't suicide, your engage can make a successful gank.
