I get the feeling that the voting selection is vague and does not specify which is which, e.g. PVP, PVE farming, Deathmatches, Red, Gray, Howlex Demons, Knighthood Bosses. I feel that the votes go to Green Gowther under the surmise of PVP.
I certainly feel that Red Gowther is superior overall. While Green Halloween Gowther only excels in PVP, Deathmatches, Red, Gray, Howlex Demons, Knighthood Bosses.
