The first point is really fucking obvious, of course you need kills for those S ranks, don't even bother saying.
Not sure about the second point, on lolsumo you are assigned a grade for the amount of wards you place, so I would assume it counts toward grades.
Third point: The further ahead you are in kills, the more farm you're going to get. It is an inherent pattern that applies in almost every situation unless you are playing something like top lane shen into trynd. You will be looking for opportunities to use your ult, while trynd consistently pushes waves under your turret. However, I have to wholeheartedly agree with this point because that's how I got kha'zix mastery 7; just abandon my team if we're not engaged in a teamfight, buy a ravenous hydra, and farm like a madman.
Fourth point: I don't think turret participation is counted toward S ranks. Even if they are, it's really difficult to take a turret completely uncontested. And turrets are not meaningless; they give global gold and each one you take is one step closer to the enemy nexus.
The fifth point kind of goes hand-in-hand with the first point.
I guess all I have to really say is that all of your tips on getting S ranks are extremely conditional and often unreliable. Dropping a ward for no reason when your ward could have been placed in the enemy jungle and saving an ally from getting caught out can have a detrimental effect on the game. Killing your laner in lane a lot is like telling me to smoke weed at 14 years old; I could do it if I wanted, but of course not every 14 year old smokes weed. My point is, you won't crush your lane every single game, and even in the games where you win lane, you're probably haven't solo killed them 5 times or something rediculous. Preserving your KDA is also analogous to the situation I previously presented. Not every 14 year old smokes weed, and not every game is perfect. Taking turrets is obviously very beneficial, but the way you presented this point made it seem like you are trying to belittle the value of turrets. And, if you're taking turrets and constantly afk farming, you probably aren't going to be killing people a lot. That being said, your tips have a tendency of contradicting themselves, because if you're taking an uncontested turret, there's probably no one to kill right?
This took 15 minutes to write. I spend more effort on these posts than I did on essays when I was still a high-schooler XD
