Been playing this for the past couple days. Currently around Level 28 in the Satorl Marsh area. I've really been enjoying it so far, for the most part. Stuff like exploring the game's world is great, the battle system is fairly interesting, and even the story's beginning to get its hooks into me. However... unfortunately, it comes with a pretty big "but" that I just don't want to deal with anymore. That being, I've really just had it with the decision to mix in Level 80-90 enemies everywhere you go with the other, normal-leveled enemies right from the first time you visit the areas instead of them only appearing once you actually got near the final-area of the game or something (as I get why they're there: to extend the gameplay by giving you things to do in every area of the game even once you reach that point, but there's absolutely no reason they need to be there until you get to that point). I mean, at first, it was fine, since in like Colony 9, the super-strong enemies were in way-off the beaten path areas and such that you had no reason to be visiting yet in the first place, so it wasn't a problem to avoid them and unless you did a lot of sidequests/exploring, it's quite possible you wouldn't even know they were there.
However... then you eventually get to the Bionis' Leg, and they start bringing them a whole lot closer to the main path, with stuff like high-leveled rhino-like enemies and at night stuff like high-leveled bird enemies near water. There's also the giant-turtle enemies, which are a high level for that point in the game, but at least those weren't aggressive/didn't attack upon spotting you, like some of the other ones I've mentioned (which is another thing: not only did the enemies have to be there, but they also made these extremely high-leveled enemies attack on sight as well. If Monolithsoft had made them ignore you, at least for the time being, it would have been more tolerable, but they attack on sight, so you have to be careful to avoid them just so you don't get into their line of sight and get insta-killed) Because of the big-open space in the area though, they were still fairly easy enough to avoid so I didn't get killed though, so I pressed on.
Went through the Ether Mines and everything was pretty much fine, but then I get to these Swamps... only to randomly find stuff like Level 70-80 Ether/Elemental enemies pretty much floating over the main path in the middle of the area, meaning I pretty much have to avoid fighting entirely/change course and go way off the main path just to make sure that one of my teammates doesn't do something stupid (like they have a tendency of doing, mostly due to these enemies getting within the range of their attacks, but still) like use an Ether art and draw their attention or while I'm trying to attack some normal enemy, one of them accidentally attacks the high-leveled one and puts me into a world of pain. And pretty much... I'm sick of it. I'm sick of having to go out of my way/use caution and alter my playing style and such just to avoid enemies that shouldn't be anywhere near that close to the main paths at all in the first place. And since it's seeming pretty clear that this problem isn't going to going to change at this point, I'm thinking that I'm going to just call it quits here, less I end up hating this game completely due to that stupid, stupid decision.
It's a shame though, since like I said, other than that, the game's pretty great and I'd love to continuing exploring this game's world, as I know that I've barely scratched the surface in this game--I just don't to deal with having to avoid those high-leveled enemies everywhere anymore. Because the story and such managed to get it hooks into me and I want to see the rest of the game's world and such, I might switch to watching an LP or something of it... but I just don't want to deal with having to dodge certain enemies everywhere I go anymore, so in any case, as far as actually playing is concerned, I think I'm done with it.
