AP update isn't bad but could be done better.

people constantly argue that ad's are too dominant and that mages are poop heads, but to be honest I just think people don't look at their mages strengths. I'll use galio and zilean for example; Zilean can speed you up by basically 100% for a few seconds, and can refresh it through his w. That's extremely strong! His q has a 90% AP ratio, now imagine that hitting someone. You'd take like 2500 from his bombs alone through a lot of ap. Galio can nunu ult everyone but with cc. He's naturally tanky, zhonyas can put any attempts to assassinate him to waste, or he can simply ult or make you buy a QSS and waste gold + item slot just for him/other cc'ers on the team. Galios flash R is extremely strong and wins a fight instantly if no support is there to clear everyone of cc. Even then, he'd have some impact on the entire enemy team and a good team would follow up and win the fight instantly. Zilean's ult is 60 seconds at rank 3, and with 40% cdr, 36 seconds. That's pretty overloaded if you ask me, and it makes the GA seem like trash. The worst thing for mages is itemization. Almost every mage is great, but itemization continues to greatly favor quick burst cancer mages like LB, Fizz, Annie, but makes sure that anyone else hoping to succeed builds raw ap/tanky/supporty to stay meta. Brand has no mobility but why does he have success? Because like most other weak mages he has CC, but items greatly favor him. It seems like rylais and liandry's were basically made for him and teemo. I think items should be expanded to a greater variety and possibly have zhonyas, GA, etc scale with CDR or just over time cooldown reduction.

TLDR: ADS have all the items they need, but APS don't. Fix that, and mages will be as strong as ever.
