Urgot is considered "Unfun" because of his strength/trades in lane
Vesh -
"Urgot has an invisible passive that means he just wins trades without having to do anything special. The enemy gets no play around it, they are just weaker when they fight Urgot. The combination of his base kit means that if you ever fail to dodge his aoe skill shot, he not only gets to do guaranteed damage to you until you leave his range, he also gets to slow you with this guaranteed damage so you cannot leave his range. "
You know what? I agree with this. I really do. But if you truly believe this Riot, then I'd recommend addressing more than just Urgot here. There are actually other champions who just 'win trades' without having to do anything special and I think you should address them all if you're going to address Urgot for that reason alone.
Allow me to take a moment to compare Urgot to Swain here, so that I can highlight what I think is a prime example. Urgot is in the limelight because he's notoriously been "bad" in the past and is now played in LCS because he's within his niche (tank meta); but Swain exhibits a lot of the same problems as Urgot and simply isn't as popular right now for whatever reason.
Without further ado, here is Swain's kit: Decrepify - this ability damages the target over time and slows them within a 900 range tether.
Sound familiar?
"...he not only gets to do guaranteed damage to you until you leave his range, he also gets to slow you with this guaranteed damage so you cannot leave his range."
Torment - this ability 'curses' Swains target causing them to take % increased damage over 4 seconds. Follow this up with any other ability for halal amounts of damage. No skillshot here friend, just click 2 win.
Sound familiar? "Urgot has an invisible passive that means he just wins trades without having to do anything special."
Last of all~~ Nevermove. Place an AOE skillshot that roots and damages your foe if they're inside at the end of the animation. If this lands you not only lose the trade to swain, but you also probably die.
Sound familiar? "The combination of his base kit means that** if you ever fail to dodge his aoe skill shot,**"... [then bad things happen - paraphrase, see above]
TL;DR - Urgot is not the only champion in this game with the issues you've described as a primary reason for reworking him. I applaud your attempts to make the game better in this regard, I think it's a great idea, but I merely ask for consistency across the board. I hope you also have Swain and other champions like him in your sights.
