in korea the daily dungeon limit is 3+2(token, here its now 2+2 (though it was 1+1 a bit ago).
Skyliner is overheat and has a 15 second cooldown
Those are the differences i know about. I think the linker nerf is universal?
Anyway, and this is important, we dont even know how separate these are. If youve ever been along for a game development ride, even a high level tester, you realize there are always many different builds of the game floating around at any given time. These builds are usualy constantly being updated several times a day or more as things are progressing, and sometimes they split off and head off in entirely different directions, with someone testing some new feature on a build that has old stuff that has already been written off. When a real full release comes out, what happens is all these changes are consolidated.
The issue with datamining the current steam patch is they could just be throwing that build on steam to test stuff, its not necessarily what we will be getting when it releases, and that build could just be something as simple as what has the latest translation stuff thrown onto it, and some of the other features could be obsolete, or things they were internally testing.
Im not saying expect it to all be different. Plenty of times you can catch new developments or future plans by looking at what these fast builds have on them, but if something seems really bizarre or out of place, there is a good chance that it was just some internal testing thing left over in that branch of the testing build and might get removed.
