Character Card System

You could probably remove Mech as Eunwol literally has only 1 active buff which isn't a hyper skill, and that's the one that blocks up to 3 sources of damage for 30 seconds and has a CD of 60 seconds. Even though I play in KMS, so my card set-ups are largely different, I believe this would be a better set-up for Eunwols in GMS

Set 1 Pirate set (PDR %):
AB for Dex (yeah it's minimal, but it still adds to the damage)
Xenon for stat
Eunwol for min crit and max crit damage

Set 2 Mage set (% MP to Damage):
Kanna for boss dmg
Beast tamer for ignore def
Evan for MP regen/ F/P for MP (Ever since they changed Spirit Bond so that it doesn't regenerate MP anymore, you do run out of MP really fast and it is pretty damned annoying as well)

Set 3 Warrior set (% HP to Damage):
DA for Boss Damage
Hayato for min crit damage
Zero for exp (If you're still planning on training)/ DS for stat resist (If you're bossing)/ Kaiser for STR (for more damage)

The mechanic thing is mainly for decent skills. I rather have 36 sec longer on each of those skills rather than 40 dex. Obviously its not needed but I prefer that over ab.
