For me these two quickfixes should be in the game
  1. Upon your leader entering Coil, a box should pop up saying entering "Are you sure you want to enter The Coils of Bahamut - Turn X"
  2. Bard should use the harp from their relic when they play songs, assuming they already own the relic

I understand there are many other issues that needs addressed, but i am sure if we all ask for fixes we want that could be small and potentially quick, for the Devs; maybe we can see it implemented into the game during hotfixes and not just patches.
