Why do people want Ryze to be reworked?
Making his combos based around is E is what makes him balanced. For example if you EWQ for a shield then get a long instant root, but miss out on high damage. If you WEQ for shield, then you high damage but a very small root time. And if you do want a shield, you delay your next combo for 1.5 seconds since you didn't go QEQWQEQ, and Ryze is known for spamming the right combos at the right time. Ryze is versatile because he actually has choices:
Do I want more damage or a re-positioning tool? Shield? Ok, then I'll have to sacrifice damage for the shield. Do I just wanna blow people up? Alright, then I will not get a shield, but do TONS OF DAMAGE.
His ult is very versatile; use it to transport the whole team for sneaking or rushing objectives; push down towers earlier. Instead of damage or free stats, his ult is pure utility. If anything they should give his ultimate a third rank, and lower his overall damage instead of reworking him.
