Many is an exaggeration. Darius and Mordekaiser are both pretty balanced after their most recent changes. In fact, I'm willing to bet a lot of people could argue Morde could use a late game buff.
You mean the same morde who is at the top of the toplaner picks from the patch he was reworked? Darius who is also an S+ pick for forever now? yea, they are not Riven or Jax, but they arent weak and when they counter you, they HARD counter you.
No single champ has the damage to burst her pre 6 so most junglers won't even gank her unless she pushes way up. Which, with proper wave management, can be avoided.
What kind of logic is that? If no champion can burst her pre-6, a freaking VAYNE! then NO champion is gankgable, unless you are gonna tell me Vayne is also tankier than melee champions.
You realise that a jungler wont gank your lane ONLY if you can solo burst your enemy right? Im pretty sure throwing vayne into a 2v1 will shift the powers.
Again, not subjective, you just want it to be for some reason. Early cheezing someone, bullying them in lane, denying them cs, and repeat killing will lead to tilting and making someone play worse. It's part of the game whether you think it's an opinion or not.
Cheesing someone is tilting, the subjective part is what people are getting tilted by, i've had games where i literally just sat under turret as Pantheon to avoid fights against a morde, and he got tilted, BM in all chat and just started diving me and feeding me.
I've had games where people are tilted because i Q them with GP, i've had games where people tilt because with 1 pull i shove them out of lane with Darius with passive + ignite.
THATS subjective, everyone are tilted by different things, and just like you're mad that Vayne is zoning you when you're Darius, some Nasus player is fuming he cant get close to a minion because Darius is zoning him from his stacks, you just dont like when the shoe's on the other foot.
Your right, Darius does get picked significantly more than those 3 combined. However, his winrate barely ever breaks 50% even though he's this extremely strong lane bullying resetting healing 1/2 his hp while on the brink of death champion (.sarcasm)
His winrate is 51.4% winrate, 9.5% pickrate,, if you dont see how he's miles better as a whole than Vayne and Tristana top, then i dont know how else to talk to your logic, the fact he has double the pickrate of 3!!! of the marksmen top combined, and still has higher winrate than 2 of those is more than enough to show you who ACTUALLY is the better pick top, No, annoying you in a matchup doesnt make you a better pick, it just makes you an annoying pick, and Vayne/Tristana ARE annoying, i will not deny or defend that, but they dont need nerfs (around their toplane presence).
The fact is he's pretty balanced having little cc and an engage tool on a long cd. Not to mention he's really just too squishy to close out games solo.
Literally everything you said here can be said for vayne too, only vayne has about 1/6th of his pickrate, and has 48% winrate, oh but she's ranged, so gutt her i guess.
