Dark Souls? It should be common sense. Someone shouldn't tell you how to get better, you as a person should already know how you can improve. Are you still 3 years old? Does daddy still need to baby you? Because this is what you seem to be.
But I'll take the bait.
Dark Souls logic can be applied to League. It's as simple as learning from what you did wrong. It's as simple as having "patience" which many do not have, and correct timing. Also prediction is a huge role, and for League, It's a chess match guessing what the other guy will do before hand, guessing where the jungler might be, knowing when to push the lane and not to overly push the lane cause patience should be crystal clear when you got a jungler who will eventually come and help.
The thing I've always hated in league, especially when I jungle is when someone dies needlessly. Dying in general ticks me off, but here's the thing. Usually all match ups go like this, we will use top lane just for the example and point. In a 1v1 top lane scenario, typically most almost all players never call for their jungler to help finish off their enemy. Granted it applies for other lanes but lets just focus top lane. So basically when you got him at 20, 30, and 40% HP, normally you guys have what I call "the death all in engage" where one of you will die. Then all of a sudden "can I get a gank?" I find it pretty fucking stupid honestly. You should have your jungler gank him when he is low always, instead of risking the loss in the 1v1 battle. Most people don't do this at all. So selfishly they want the kill, they are willing to die for it. This does not help the jungler, instead this puts your lane opponent even further ahead, and even 2 levels ahead of your jungler.
What's even more dumbfounded is when they don't even ask for a gank even after the first death from the needless 1v1 fight, instead they teleport back to lane and attempt the same exact thing. Granted you can probably get the kill, you may have misplayed the first fight, I've seen the tables turn back into the favor of my teammate, but more often than not, it wasn't a misplay, it was a mismatch and runes probably played the factor along with masteries. Now after you die once, typically the other person recalls and gets another item which gives them a slightly bigger advantage. In pro play, this is a gigantic huge advantage cause they know how to use that extra item, and are good enough to make it work.
So just call for the jungler before the first death fight.
Also, I hate when people don't ward their lanes, and ignore all the warnings from the pings being sent. I see this all the time.
