By the way, more freedom? lol
You could've gone without that comment. Feel free to explain it though, because you certainly didn't want to in the video.
I think that what the "freedom" comment might be getting at (essentially) is that the surplus "road block" system allows them to make the EXP curve less steep. That being the case, if we start playing on Monday, maybe we get to skill level 15 (or whatever, just for the sake of example) on Thursday and then hit surplus, and we have Friday - Sunday to do other things. Or if they removed the whole surplus system they would make the EXP curve a lot more steep, to the point where we'd only be getting level 15 in that first week anyway (barring some really extreme hardcore play or an exploit like SMN burn in 11), but we aren't able to hit 15 until the end of the week (and casual players wouldn't be able to hit it at all). We have to use more of our play time to do it. So the "freedom" comes in a sense that you can still get level 15 in that one week time frame, but only spend half the time doing it so you're "free" to do other things you may want to do.
Not making any judgment calls on it or saying that those are the only two options, just explaining what I assume is meant by the freedom comment.
