The 10% thing is VERY LIKELY [edit: nah I’m dumb and wrong - but I was also looking at the alternative very incorrectly] a boost to the effects of skills for each rank above the skills circle / rank you are. I mean, it’s a very important balancing issue, which brings the first few rank’s skills on an even playing field with the strength of those later on (just look at the damage differences, comparing a max leveled early rank skill to that of a low leveled high rank skill). Especially now that you can pick up lower ranked classes at a higher rank, it’s very much a balancing thing.
This is in contrast to the addition of 10% to actual stats, of which makes very little sense and seems kind of arbitrary if done literally, and gamebreaking if done in a way that rewards picking up as many 3 circle class sets as possible (this promotes less freedom in terms of choosing a build). [So it’s just a 10% boost each rank, which I honestly find kind of dumb, but I guess they need to it so people but some emphasis on not con or dex]
Also, the mercenary guild seems to have some stuff going on now, but it seems very unfinished (before, the guy would just tell you to come back later). Also, the additions are seemingly unrelated to the instance dungeons (you can choose from a list of maps, but nothing happens when you do, and there’s nothing new on the map, at least for Gele Plateau).
