Hmmm, Ryze, huh.. His stun plus AP burst sounds like a good plan.
Yeah, I more than likely do poorly against her as a favor melee champs a bit. I played a game today where she was low, and I had about double her health as Olaf with arm pen, lifesteal, and armor, but nope she killed me in a few seconds and walked away with almost full health. This was reletivly early, too. Than she roamed, snowballed, and just destroyed people. Kinda funny, acually. The summoner knew what thet where doing.
On another note, I can counter all 3 juggernauts with Olaf. Build resistances, speed, and get at least 2lifesteal items. If they go armour, which they will for deadman's I up my true damage. M i lking lifesteal allows me to outsustain say, a Darius. I do AD reds and quints, cdr blues, and armor yellows; start flask, 2 health pots and a mana potion for sustain since masteries (21/9/0) and runes let me start 81 AD, which is good for Olaf early as q and e scale with damage, if my memory serves me correctly.
Anyways, I should pick up Ryze, you're right. If she can't move, she can't hit vitals. Plus AP damage cheese.
Although I've heard a lot of people say Ryze is weak atm. I destroy him with Olaf, but have seen ONE Ryze who was very good with him, and mopped the floor with people.
