It depends what you want to focus on though. You are getting 4 less leves overall but are being allowed to focus even more on any specific thing. Don't forget the battle changes that will most likely be making enemy grinding more rewarding and this system is tailored specifically for those with less time on their hands, who benefit immensely. I'm also willing to give up those extra leves to be able to marathon them 2 days a week, personally. I see the point on guild marks but those come easily enough as it is nowadays and I'd easily take this more flexible system anyway.
