So, I would like to discus the fact that after a certain time in the game (usually about 35-40 min) tryndamere can pretty much solo an entire team and win. This needs to be changed. just lost a ranked game after my entire team went positive. We were literally on the winning push and tryndamere just backdoored in less than a minute. solo. with one minion wave. How is that in any way acceptable? I'll answer that for you: its not. Riot please do something!
Not sure how his buggy as shit ulty has anything to do with being able to backdoor properly.
I admit he can be hard to catch, and I feel is E needs to have more CD so that his backdoors are not that safe, but the solution is always killing him before any TF or simply ignore him, he can't take down Nexus alone as fast as a complete team would.
Also he is unable to solo vs 5, you just have to wait till he blows his spin and just slow him down or CC him, when he is down just count till 4.5 and then land your damage, it has always allowed me to kill him.
also helps a lot to fight his slow, and 
will prevent him from catching you totally.
can you see my custom item? I've made an icon for it! http://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/buOIBEzA-the-phoenixs-talon-icon-made-by-me-3
His entire kit is designed around 1v1ing and split pushing. Tryndamere is not a good teamfighter and should not be able to 1v5 and win. As for the ult, it's clunky and only lasts three seconds, if you can CC him he's a goner. His ult is also a little wonky as of late, I've seen people not get the undying buff and die immediately after activating it.
If tryndamere could 1v5 that's on you, you fucked up.
