i see they decided to delete black mage.

you know you can put a wizard hat on any class you want, right? The hempen hat works on any class from level 1.

Even still, If it's a valid reason to make any class baby-stupid-easy just because it's a basic fantasy archetype, then where do we draw that line?
I don't like Dragoon's gameplay, but I really like using a spear. Should I whine on the forums until Square makes it something I'd enjoy more? I probably would be a bit happy to enjoy Dragoon for the twenty minutes I try it before I go back to playing something else.
Hell, I started as a Summoner in one of my early characters, but swapped to Black Mage because playing a Summoner felt like I was a three-year-old chewing on building blocks. I want that job to change to require a bit more than a single digit IQ to optimize.
What's the main stat on Caster DPS again? Intelligence. How about we try to fill that class fantasy.

Why should one class be 10000x more complicated than any other class in the game? The appeal of black mage is that it is a pure magic caster with no frills. You just spam your strongest magics as much as you can.

Black mage at its core is about purity, not complexity. If any class should be overly complex and intellect based, it is scholar. You know? The one that is titled scholar? Black mage should be a dps version of white mage. Purity of magical expression, not complexity.

Talking about IQ in an mmo is always going to be a silly thing to begin with. You want to use brain cells? Do science or something, become a doctor, engage in literature. Video games, mmos especially, are not an intellectual activity. Like rofl, you play mmos and you're trying to flex IQ with it, do you ever take a step back and realize how inane this idea is?
