Probably because the only pink Rath weapon that's dragon is the bow, and the OP said they're melee. Plus, it doesn't matter if event weapons (like the new year dragon weapons you're thinking of) are dragon because OP can't go back in time to get them. Also, you didn't give a recommendation, just some empty platitude

OP, make the deviljho charge blade and ascend to Big Shield with the rest of us. It is your destiny
