all too often the lane was gankable before the laner went 0-3, and he wanted your help, but you felt one way and he felt the opposite. now hes 0-3 and now youre quick to label him as the problem and the game is going to be lost because that laner was bad.
i agree, your efforts can be better spent somewhere else.
BUT... BUT
you ganking before 0-3 completely dictates the rest of the lane, instead he gets a kill and is 1-0 to start with a longsword advantage and stars winning earlier on.
this is all a direct result of you feeling you cant make it from blue side wolves to top lane in those 20s from when youre at half health, your laner is at 1/3rd health, and the enemy top laner is at 3/4ths health winning.
let me tell you from experience, 2v1's pre first back, everyone goes down quickly, i dont care who you are, if there are two of you showing up to lane even with low hp, it doesn't matter, any hard cc or person who can take 1 or 2 auto attacks or abilities is enough for a low hp laner to contribute back to the fight so it wont just be you 1v1ing that top laner from a disadvantage. instead its two of you providing burst because no one has resistances yet.
i can assure you, you've already lost the lane for him because you perceived him at a low hp total, and the enemy (whos more than halfway down the lane) is ungankable because you're not comfortable 1v1ing. well guess what, its never a 1v1, its a 2v1 when you show up.
a blitzcrank with 1/3rd health and is 3 levels down has no problem showing up to fakers lane and providing just a single hook to him which nets faker the kill, and its not because the laner is faker, its because the blitzcrank knows all the damage is there already, he just needs a setup to make it happen.
when a laner is 0-3 and levels down, you're right, the lane is no longer gankable because you cant 1v1 and your laner isn't providing squat. but understand, you helped create the 0-3 lead for the enemy team when it was completely reversible, i just hope you get something of equal value in return somewhere else, THAT is what makes good junglers. but i bet you sit in jungle and powerfarm and hope to show up at the right place right time.
the only thing that matters before level 6, is the two champions positions on the map and who throws the first punch, all too often junglers refuse to gank an enemy whos on your t1 turret because you're not 100% health, you dont have a lead or a certain item, enemy has summs, or even just a level powerspike.
in addition you repeatedly play ww regardless of the game or what it calls for, so yes YOU lack damage a lot of the time so if the laner doesn't have any, and you dont have any, its completely pointless to go there. which is the correct call, but understand there are other junglers who can turn that situation around.
but your duty as warwick is the early game, you literally win it, and here you are, allowing the 0-3 situation to happen in the first place when you should be 3-0 and putting some laner into the dirt because they cant use summs when feared and they aren't going to be outstatting you or winning without items against you. but here you are, in the jungle perma farming declaring lanes ungankable, you mean "not free for me"
