If you're posting living in your fantasy world and wanting people to agree with your poor decisions to feel better with yourself, please go the heck away.
You make one mag per character per stat. That's how it has always been. That's how you do it for free. That's how I've done it for seven and a half years on the JP server. Phantom became the exception, however you do not even necessarily need a DEX mag to make phantom work, it only makes all three available weapons work at the same time on the same character.
Get off your high horse. There's no perfect do-everything mag, that's not how this game works. Statistically it is not possible. Points spent not doing what you're playing are points wasted. That's simple kindergarten math. 200 is greater than 50. If you don't want to commit then stop begging people to agree with you when it fundamentally does not work. Defense is crap because it's split three ways. 0.33 is less than 1, you might see.
Now, you can play whatever the heck mag you want doing whatever the heck you want -- nobody can nor should stop you. But saying, or somehow begging people to agree that it's the best way to do it, when there's clearly much better alternatives, makes you simply wrong about it.
But I don't think it was ever about anything at this point; you've plugged your ears to explanations and la-la-la-la-la'd your way through the thread. I've personally explained why it doesn't work at least twice now, so that's clearly not your goal.
You're right. You did it. You found the perfect mag. Congratulations, you're the best in the world. You beat the game. Good job, sweety. Don't let that mean old Rockbear tell you otherwise.
