Tryn is one of the most underpowered champions in my opinion.
Yeah sure he's got some early crit and AD, but he doesn't really have anything but that and a slow. His ultimate doesn't do well against any team with a brain.
There are much better melee champions, like Yi, Nasus, Riven, and Wukong.
Yi has his meditate, plus a better passive AD skill, and his ultimate is way better than "fill rage up and not die". He gets a massive speed boost and cannot be slowed. Whenever he gets a kill with his ult active, all his cooldowns refresh. This makes him highly viable with AD or AP.
If Nasus gets a free farm, he can be an ultimate tank that kills you in 3 hits. Not to mention that his slow is equivalent to actually chopping off your legs. It's not just a movespeed slow either, it slows your attack speed so Tryn would get eaten by Nasus.
Riven is a great melee AD caster who can quickly dance around the enemy causing interruptions. Her ult not only improves her other skills and AD, but also grants her with an AoE ranged Garen ult. All 5 of her skills (passive QWER) scale on AD. She only ever autoattacks between her skills. Don't build too much attack speed on her at all. You can rip people apart with Riven if you can use her right. Can easily interrupt and shield (scaling on AD!) vs Tryn and as he ults and spins away, throw your ult at him. If he spun away early, start broken wingsing and shield dashing your way to him and then throw it at him.
Wukong is usually underestimated. His crushing blow is devastating, as it throws extra damage on you and lowers your armor. Decoy is an awesome Shaco-like skill and you don't even have to use it. If they're expecting you to use it, just stop moving and they'll run past you. His nimbus strike is good for farming and gap-closing, activating your crushing blow just before it causes a nice burst. His ultimate is a beefed up Garen-spin that knocks enemies airborne. His passive is also highly underestimated or often forgotten about. It increases his armor and magic resist depending on how many enemies are nearby. When he strikes, blows, and spins his way into a teamfight, he's going to take some effort to bring down unless you let him kill your team. He has a base armor of 78 and base magic resist of 52, while also gaining 8 per nearby enemy champion, going up to 108 armor and 92 magic resist without buying a single armor/mr item, or using any masteries or runes.
Tryn can do a minispin, slow, and not die for a few seconds while doing nothing considering if he's on the team, people will make sure to do just enough to make you die and not live. Or at least keep you out of the fight (with ease) while they butcher your underfed team. (cause you keep taking all the kills then die lol!)
