i was in the shop trying out the pin offer for today (im used to get avatars and pins, i love them)
and noticed this golden frame arround my avatar. i just loved it. is already in the game on the shop. i would gladly spend gems on the store to get some cool frames,
or you could also give them daily as reward for the top 10 players local and global. that way doing raids and climbing the leaderboard would not be a waste of time. anyway sell frames, give them as rewards, whathever, just give me the chance to get em! i bet you could be creative making new frames.
