Ryze is complete BS
He's such an absurd champion right now. if there was ever a champ that could be called a sustained burst mage then ryze would be it. Part of his dominance is the strength of mage items right now. For a supposedly squishy champ hes really hard to kill thanks to mage items. Morellos, roa give him a huge healthpool while items like seraphs give him a great defensive active and zhonyas is total bullshit to be completely honest. Then you throw in ravenous hunter and you suddenly have a champ that can heal almost as much as vlad, can kite amazingly well thanks to passive, is hard to kill if you do manage to get on top off him and has some of the best waveclear in the entire game. Riot needs to admit that they cant get this champion right and do something instead of their typical rework where they leave his kit entirely the same and just change the numbers.

any combination of these items, and as long as they have 
they will deal great damage. He doesn't have exactly 100-0 burst for most the game but he isn't like all the other burst mages where after you unload all your abilities you kinda just waddle around fights waiting for cooldowns. You kite ( with phase rush because your a gentleman and not a conqueror abuser ), position yourself, and drop more EQ bombs. Even if you completely fuck up your early game and go 0/3 in lane, you can still just pick up side waves and jungle easily and wait for your power spikes. I really think more champions should be like Ryze in a way. Where they don't have to build 100% damage to keep up with everyone else's oneshotting. So teamfights can actually play out and not just be oh looks like I instagibed your carry so I win.
