I like Colesteel 1 so far but I have a couple of concerns
>Arcus/Link system breaking the fuck out of combat(yeah it was broken but never off the bat like now) because everyone can effectively hit twice with unbalance/detector.
>Sepith Masses breaking economy(Again, was always broken with shit like the EBC but at least you were giving up your chance to synthesize quartz in the process
>Quartz being nerfed by placing absurd importance on master quartz giving you the bulk of your arts and not what type of quartz you have slotted, I liked the Ao system of master quartz+quartz more.
>Animations a bit awkward. Sky/Crossbell weren't the best lookers but they at least tried their best with the artstyle they had and I actually liked some animations like the troupe ones or the combat ones against ouroborus. Here everything seems very stiff, like an old animatronic.
>While on the subject, everyone(sans gaius I suppose) in class 7(and a lot of people outside of c7) seems to share the same facial and body structure in terms of model. This is something I've noticed with the portraits in Crossbell(how Lloyd and Elie share the same face/eyes and the only difference being their hair) and the party Ys games(Laxia sharing a face with Adol) Laura's supposed to be a built amazon according to the dialog from the gym but she's practically a slightly taller alisa. Fie's a scaled down alisa and emma's just alisa with glasses. Rean and the other boys are just alisa without breasts and pants instead of a skirt, it just gives off the same model being reused over and over.(Which yeah, sans a few exceptions like Zin in Sky was the case in Sky but then again not much you could have done with that artstyle)
I know the last two are graphics whore shit but it's hard not to notice, especially since they went with a neat little 3d engine and all and I guess that's not changing until Kuro.
