KMST 1.2.435 - Luminous

Well, if they do release 5th job, it's going to suck if 5th job has mastery book requirements.

I'd facepalm if it's Mastery Books again. I'd like to see something new, Mastery Quests or something.

We're gonna get screwed if there's skill requirements for 5th job due to 4th job mastery books.

Example:
Expert Combo Attack/ EX Adv. Combo
Req: Level 30 Advanced Combo Attack

Can't afford ACA 30 because it's too expensive or many tries and still won't pass? Too bad, you'll lose out on even more damage. (I'm sure we all remember when ACA 30 was 100m+, even 200m in Scania earlier this year)

If they decide to release 5th, hoping they scrap this whole Mastery Book system & replace it with something more interesting that isn't so limited. Hell, I'd rather collect 1,000 of an ETC to raise mastery level.
