Okay...this is what I've gathered.
As far as I'm concerned, you're mainly saying that Excalibur is the best weapon in the game, the Calculator ability is the best in the game, and that Haste is the best status in the game. This is all that I have gathered. You're basing everything on those three items. While I'm trying using the Monk's abilities to my advantage, you're using the Calculator's Math Skill to your advantage. And so, I now bow down in respect; to a certain point, however. You should consider changing the title of this thread to "Excalibur is the best weapon, and I am ready to defend that statement." Just food for thought. If you're gonna say that Knights are the best class with other abilities, don't make them depend on one weapon. That's just what I think. If you aren't going to make them depend on one weapon, I sure hope you pick the Monk class as the best class with other abilities because they are. And as Big Ogre Umaro said before: "I don't have any fun when my characters are too powerful." This is just getting boring now...*shrugs* *thinks you should change the name of the thread to "Excalibur-Equipped knights are the best job class in conjunction with other classes, and I am prepared to defend that statement."*
IF the Equip Sword ability could be used to equip Excalibur on anybody, then, yeesh, they'd all be able to kick butt. Even Summoners with Short Charge, Excalibur, and Calc. could beat your knights.
But, heck, just have 5 female people, all with Chantages, and then I could call it a day...
