Colorblind mode doesn't help with all forms of colorblindness, I would know.
For example, I cannot even see Battle Boss Ziggs's abilities at all, they're just a blob of gray floating across my screen, along with a gray landscape. Please add specific modes for different types of colorblindness, it sucks that I can't play the game at the same competitive standpoint as everyone else due to a birth defect, let alone people spamming missing pings over my head because I'm walking into abilities.
