I don't need em. I wrote out thrice or so how it could be fixed with minimum work, without actually changing Blue Mage from what it is. I won't bother writing it down again.
Blue mages have only Blue Magic. As far as "artistic freedom" doesn't stop them from having some other skills, they will simply not be numerous enough to make a serious difference. Even if we'll assume they'll get ten of them, it's still way too many skills lacking. And if you'll add more then you may as well make another job entirely.
If that was the case then all this stuff about limiting wouldn't even be necessary. The spells of Blue Mage will most likely contain some unusual spells. Ones that ignore resistances of boss monsters (the video did show Shiva stunned, which is impossible normally), for example. The moment you start banning individual skills, you end up with tons of work. And what's stopping players from stacking the high-cooldown, high-damage spells for a massive burst, either? With twenty skills and ~2,5sec cooldown, that's 50sec of casting massive spells one after another. By that time at least some of them will come off cooldown and the party starts again.
It's already in there. You need lvl50 job and have finished 2.0 main story quest line.
Besides, it doesn't change anything. I've come across people leveling their alt job, with several lvl70 jobs, that didn't show basic understanding of the game or lacking respect for the time of others. I have no faith that these people would go way out of their way to get numerous skills for leveling if they think that others can carry them.
Progress means various things. It doesn't only mean getting to the end-game content and rushing through the Raids and Savage. It means being every time you log in further in something than you were. For certain people it may mean getting a new minion, for another defeating a different NPC in Triple Triad. The purpose of a game is first and foremost to have fun, the means of doing that don't matter...unless you cause grief, that is. I don't get how cooking can be fun, or doing house chores, or eating. I do em cause I need to. There are people that relax by cooking, cleaning or eating. Should I dismiss their way of life just cause it's different than me?!
But every current job allows a bad player to finish any dungeon in the game...almost. So long as they are trying, that is. Blue Mage does not. If you are a bad Blue Mage player, you literally are useless, therefore you're going to be bashed more often and harder than if you came in with any other job.
That's completely out of the left field. This discussion is not about complexity of a game. Personally I abhor the dumbing down of everything that Square Enix seems to enjoy. But, again, that have nothing to do with this discussion. If every class had some sort of quirk like that, sure. I'd love that. The bad apples that don't want to learn doing a thing wouldn't be able to go past first two or three dungeons and only the average+ players would be seen in later stages of the game. But as it is, they'd only change from Blue Mage into another class and continue being detrimental to the community for the rest of the game.
