If a clan is already at level 30 plus, they most likely have already used their double xp. Going to a lower level clan would be a good choice. if your wanting to do that quote me so i know you replied or PM me, I'll invite you to my clan. Im the only founder so far D:
I will give you each 2 hours of double XP for joining my clan. I have over extra hours on my www.dewxp.com account. Once you join I will put two hours on each of your gamertags, seriously. Message me! The clan name is SwagBrigade you can find us on the site or on the xbox app! Hope to hear from you soon!
