Apparently, it's not best to go on full MATK because of GTB and Maya Card. If the situation calls, you're gonna be needing to using cart term to deal decent damage and at the same time, hopefully proc the chance of breaking their armor. and about the buffs thing, GTB solves it all. luckily, WS are semi-tanks having 300k+ HP, so they can bear the damage that the GTB penalizes.
All in-all, i'd be very pleased on getting this suggestion be reviewed for further balancing of ws gring. +1 to this
