I already have Tendo and Ay, but I don't have the 1st Hokage. I've got 25 frags of his so far and a combined total of about 10k in coupons/ingots. Would you recommend going for him in this event? I noticed that he's rarely ever redeemable in events anymore other than in those Hokage optional gift packs, which is why I'm thinking about getting more of his frags. I have all the other Hokage for what it's worth.
