Yes, I'm aware this has been complained about before multiple, multiple times, but I'm sick and tired of going into a game and having to deal with a Tryndamere who gets fed off of my teammates and then literally can't be stopped. I just got done with a game as Varus where I went 15/5/12 and we lost because their Tryndamere - complete with Berserker's Greaves, 2x Bloodthirster, 2x PD, and an Infinity Edge - kept waltzing into our base and backdooring us with 450+ AD and an AS that made him impossible to kill; the Lifesteal was bad enough, but adding in his Ult made the few times we got together as a team to pounce him impossible to kill. He'd just flash/spin away while killing 2-3 of us at a time because of his ludicrous Lifesteal/Damage making even a few seconds of combat unbearable.
Part of this, I recognize, was because my team had horrible composition... but it's not like it was just this last game that it happens. I don't care what gets changed, but his ult needs changed; period. Even halving the duration would make him not so almost completely unkillable early game, which then leads to him being outright OP lategame. Hell, in the last few seconds of the match I was literally pounding on him with 300 Damage, 1.9 Attack Speed, and hitting him with an ability every single time I got to 3 stacks of Blight, but he just used his ultimate and wailed on our Nexus until it was dead.
I understand it's important to CC him, yes, and I understand Exhaust/Ignite/Stuns are your friends especially EG, but there is no reason a champion should require so much concentrated counter picking all on his own. The only champion even close to this ludicrous level of survivability is Mundo, and at least there's an item that's mostly effective at dealing with him.
Please either reduce the duration to something like 2/3 seconds like Kayle's Ultimate, or at least make it to reduce only 90% of the damage or something. At least with a Champion like Shaco, Morgana, Rammus, etc... you can kill them, shut them down early game. If you don't shut down Tryndamere by level six, he's virtually impossible to kill, and I can't always be the team Captain to ban him. Otherwise you can be assured he'd be my first ban, every time.
