One hundo percent true!
If there's one thing we know about the casual majority of players it's that they 1) play the game on the side and 2) really really care about doing maximum DPS and 3) wanna have an easy time parsing without much to think about.
Same as casual DPS players of course. Which is why we frequently hear DPS players crying about how much room for optimization there is with their kits, tanks too. They should all be like healers or preferably easier (who hasn't been having an anxiety attack because they mistimed their Dia by a second amirite fellaz? Casual time!).
And Sage is really the job for more toxic brained players, which is why they have Phlegma ballz and that's it.
The most important thing to remember is that you should never feel like the game is too big and there's too many things for you to learn or that you can improve your skill. That makes the game feel intimidating and it can't be played casually anymore - you have to always already be able to do maximum DPS - to casual players learning a game isn't rewarding, being able to become better isn't fun, it's the opposite, it ruins the fun of already being at the peak and there's nothing that casual players want more than to feel like they are among the best players, that's a casual mindset. The toxic elite doesn't understand this, because they only care about being better than everybody else and they don't like casuals being equal. They only pretend like they think a high skill ceiling is fun, in reality all they wanna do is ruin the game for casuals.
