We really need a global CD increase and mana regen nerf.

Casting spells needs to count, it should be in a way that rewards proper management of mana + uptime instead of being able to carelessly hit Q W E knowing it won't make a dent in the mana pool after level 6. This is the same for CDR, since it's so easily to access CDR as any role, every single champion should have their spell CD increase to punish bad casting. This way it restrains CDR creep, CC creep, mobility creep, and prevent heal/shield bots from having near 100% uptime on their heal/shields.
