Havent done anything but the combos and skills and just trying out the classes, but from what Ive seen, I'm surprisingly happy with it
Now if they just gave up on the idea of moving = spellcasting stop..and the 420 MP per heal (when 1.19 came we complained about Heal going from ~10MP to 120 MP, and what do they do with 1.20? They raise it to 4x the amount of 1.19..)...and the extreme distance needed on archer to get combos..and all the stuff people will complain about in the upcoming days, about low drop rates for moogle weapons, achievements no normal human could gain,..and so on
Yes, in THAT case, 1.20 would be a patch to make everyone happy x)

Okay, I have to start new rage threads now about everything I talked about here..*walks away*
