Can we just talk about Tryndramere for a second?
I'll be completly honest here: you could take Tryndra's kit and strap the title "Outdated piece of shit that should have never been released and should have been reworked AGES ago" on it. You thought Teemo was frustrating? At least you have that sweet feeling of relief when you finally kill that satanic incarnate. But with that guy? No, fuck it.
You can have 5k effective hitpoints, 200 armor, a randuins against the crits - it does not matter, you die against a glass cannon build in 3 seconds that for some fucked up reason has a FIVE SECOND INVINCIBILITY on it - not to forget the slow and the AD reducer so you can forget trading OR escaping in the first place.
But let's just try to be objective here and figure out just why this guy needs a rework:
1.) Crit dependence + plus the first half of the game is pretty much "either I'm lucky or get crits and stomp you despite having no skill andI let luck decide the lane" or "I do not get crits but still am relevant" because 2.) He gets rewarded for playing PvE 75% of the game. Wasn't there a major design headline somewhen in the past? "MEANINGFUL INTERACTION"? Well, guess what, this champ is the complete antithesis of it. Either he completly AVOIDS all kind of interaction (not fed) or, when fed, denies all interaction apart from murdering you because of a: 3.) Complete lack of effective counterplay. Yepp, kiting sounds nice and all, but against a spammable, walljumping gapcloser AND a unavoidable slow that's SUCH a good idea, no? And you want to trade? Enjoy your reduced AD AND a time window of 5 seconds where you cannot kill him but he can surely kill you five times over.
You know, I can get people getting mad when a Riven kills them. But hey, at least that Riven player invested some kind of mechanical skill into that - meanwhile the Tryndramere player just slams his active items and rightclicks you to death - while you can do nothing apart form putting his ultimate on cooldown. Feels completly fair, no? Also with the armor nerfs buying item against that seems more like a joke to me.
I honestly don't give a shit if he's strong or weak in pro play, LCS or whatever: he's just frustrating as fuck to play against. I personally dodge every game with a Tryndramere by now - not because I think we would lose 100%, but simply because this champion's presence in a game literally sucks all fun out of the match. I would ban him, but sadly the balance team STILL has not nerfed sated devourer and too much shit is OP atm to throw a ban on Tryndramere.
Rework that guy already - he's a standing monument on how you can screw up a melee champion design.
EDIT: I am impressed: 5 seconds and there is a downvote. Apparently Tryndra players react sensitive to someone even TALKS abotu touching their precious freeElo...
then your gonna have a bad time. Also he wasnt even very fun to play .
Check your check list.
are relatively vulnerable to getting ganged up on and removed from play if they push their luck. With Tryndamere, it is near impossible to really get rid of him no matter how far he has overextended because he has a massive wallhop dash, movespeed from his crit items, and if all else fails, guaranteed 5 seconds to live and find a way to get out of the situation. Then he comes back 30 seconds later to do it all over again.

. She has stuns and slows for days, can cram a wall in his face, and will just egg if he dives her.
