>>42528308EX Korrina is the only bullshit one. You need the right mons and you need to play near perfectly to beat it, which is only hard to do because pubs tend to be retarded. Everything else is doable to laughably easy, you just need the right mon most of them. The REAL problem is the drop rate fucking sucks dick, making 2* gear needlessly tedious. I honestly would prefer the stupidly hard challenge if I was at least guaranteed a 2* gear and the appropriate amount of material to upgrade it go with it as a reward for every battle. DeNa is too fucking stupid to realize that leaving your game on auto for hours isn't fucking content
