Here is why Tryndamere is an unfair champion

You can't beat him level 1 or early game because it's a risk that you don't know if he is gonna crit or not, so you cannot punish him because of League of Legends bullshit crit RNG.

Gets free AD and gets even more AD based on how low he gets, you cannot 1v1 this guy because you think that you almost killed him then turns it around because he gets free AD and kills your team.

Lowers AD from all nearby targets by upto 80AD, lets just take two BF Swords worth of AD and gold from an ADC on a W press.

Building armor to counter Trynda does nothing, because he takes Conqueror that gives AD + free AD in his kit and he also builds IE that has true damage with crits. And if he builds AP, then you done. Good luck trying to counter a Hybrid champion. Just the idea that an AP build works on Tryndamere shows that there is something really wrong and unbalanced in his kit.

But my biggest problem with his fucking kit is his Ultimate. WHY THE FUCK CAN HE USE ULT WHILE HARD CC'ED? THAT IS BULLSHIT. If you CC a Yasuo or Master Yi or any other champion then you can kill them, but not this fucking champion. You use CC to try and get this guy low and then Tryndamere uses ult and your team has to wait 5 fucking seconds. If Tryndamere gets hard CC'ed HE SHOULD NOT BE ALLOWED TO USE ULT. The only counterplay to Tryndamere ult is kill him in a huge burst before he has a chance to ult, or if he presses his ult too early. That's the only counterplay to his ult.
