Most of the complaints you listed pertain to mages more than any other class. Mages are the only ones that don't have actual "tank buster items" which only because a problem when Tanks got a major rework. They were overtuned, but instead of toning them down, they toned up AD items to deal with it, thus putting them on even footing with AD, other tanks, and bruisers. However, mages got left behind.
I agree, this item update doesn't really put them on par with other classes in the game. It makes them even weaker than before, even with the stupid 10% cdr on Zhonia's. I mean, they increased the cd on the active and reduced the AP... by a lot.
Yeah, we have some good utility items coming, but soon the only mage that will have any bearing on the late game will be Veigar, a time which I would kind of like (Veigar main ftw) or mages that have incredible cc abilities that are pretty much instant-lockdown spells.
