this no skill freelo champ
he actually does take a decent amount of skill. Overly rewarding, yes, but still takes some skill
has been dominant for too many seasons
you mean season 6? Because it's not season 7 yet and season 6 was the only time in a longgg time he has been dominant. Needs nerfs? Yep, but let's not be wrong because of salt
He can build whatever he wants and get away with it
now...that's just not true lol
and he does as much damage as a riven while being as tanky as a rammus
not unless he's enormously fed and so he gets carried by his armour pen and is allowed to build tank. But if he's normal, he definitely can't go tank without losing damage
your opening paragraph is riddled with false statements
he has no cooldowns, no resource to manage, abilities that proc lifesteal affects, AOE CC, A SPELL THAT NULLIFIES ALL PROJECTILES (INCLUDING ULTS)
I can make any champion sound OP if you only state their strengths (especially if I overaggerate them like you did) without looking at their weaknesses.
There is not a single sentence in this post that would even be considered worthwhile to read for anyone that could actually change yasuo. Yes, I dislike him but even I recognize this babyrage thread better belongs in the Miscellaneous forum
