Best. (Or, barring that, Seven, to get FFVII fans to shut up)
No, seriously. I'm sick of forum topics about RPGs in other places with level 1 people who have clearly not played for 5 minutes demanding to know what nthe best everything is and how to get it ASAP. "Best" is subjective. Are you looking for the best damage output at the cost of 80% of your defense? Are you looking at the best support at the expense of some attack power? If there was one single setup that was the best for everything, it would be utterly pointless for anything else to exist, so why bother MAKING the rest of it exist!?
I want to ban this word from forums SO hard.
