While I agree oGCD lilies are bad, APM isn't really an issue because players who struggle with high APM and have conditions like arthritis generally aren't keeping 100% GCD uptime or doing harder content. They'll just press the buttons at whichever pace they're able and that's fine for everything below Savage.

I disagree with designing specifically classes for people who can't handle more than one button press every 2-3 seconds. Remember they've already designed the content to cater for that type of player. Everything from MSQ, dungeons, Normal mode and even EX has extremely low or no dps requirements at all and is intentionally designed so every type of player can experience the game (which is great). There just isn't a need to butcher the classes too. Even if WHM had a bit more APM when optimized, you don't need to optimize it in Normal content and nothing changes there.

Slightly off topic but I'm tired of the concept that WHM must be the "simple" class with no skill ceiling when we already have accessibility built into the content.
