It impacts everyone with a battle banner. In particular if that battle banner gives more bonus than lucky casket.

If the battle banner gives 10%, then we can open a legendary chest after 48-10%=48-5=43 hours. However, if we don't have a lucky casket, the server silently subtracts 5 hours worth of gems.
