[Unanswered]  wyvang's type

hey i been on the wikia and i just got the zero g ultimade stamina & defense set and ive been able to do the anime combo archer wyvang 145wb, after looking at the stats i see that wyvang is considered a stamina ChW.
cobined with archer(attack/balance) and wb(defense) and also how it performs in the stadium (zero g and normal) 

¿is archer wyvang 145wb a defense type?
I would call that Archer Wyvang combo a mess.

Its marked as Balance, but Wyvang can be used for both Stam and Attack. Archer is... Pointless. WB is more Stam than defense. 145 is certainly not great for attack and not amazing for Stam.

It's called Balance because it doesn't Excel in any particular area.
