Taking the OP's idea on, how much would it affect the state of the game for Cav and above summoners to have access to a 2015 Nexus selector? Maybe for 150000 6* shards or something?There's no Hercules, Doom, BWCV, Kitty, Tigra, Apoc, Human Torch or Immortal Abomination to imbalance the meta but plenty of classic champions. This might be a nice placeholder until when/if we get the Wish crystals. And we know for a fact that even if these champs get a buff ultimately it will at most be a moderate one.
