I don't care what you say hes bad hes not overpowered silver scrublords he can easily be beat and has a bad winrate and isnt even good if fully mastered he needs buffs.
Buff Jax please1 votesYeah he is pretty useless at the moment. One of the champs where dodging usually makes sense when you have him on your team in champ select.
specter4241 votesmaster yi was for the longest time a shit champion we saw how things go when he is viable outside of silver I don't think anyone wants that to be changed.
BoilTheOil1 votesno hes always been pretty descent
paisy1 votesThey need to revert the ult changes
God King Aatrox1 votesi played Yi like 2 days ago. 
was my build, safe to say, when i dived the enemy carry, i would nuke him, or force the entire enemy team to waste all their cc on me, letting my team to do w/e while they focused me.
Won that game.
point being made: he's fine if you know what to build and how to make the correct moves.
BoilTheOil1 votesyou just did good that game
God King Aatrox1 votesfunny enough i was actually pretty underfed most of the game, when i ganked id either get nothing or an assist. i was behind the enemy mid and enemy jungler. i could of done a lot better pre 20 minutes but i made awful decision making up until we started grouping, i just did what i had to do in teamfights.
BoilTheOil1 votessome games you can do good or bad it depends on their comp or if you get fed things like that its pretty much luck
God King Aatrox1 votesmy point is on your OP you say he's weak, when if you dont build him glass cannon he's a niche pick if you need someone to dive their backline.
