This is why I can agree that Epic requests (not the donating, which anyone should be able to do) should have a minimum level restriction. It should be for the players who have been here for some time, have way more Epic DNA than they need and need the help finding those few strands to level up their own Epics.
I also don’t think it will hurt weekly Alliance tasks at all. Players and their Alliances will still need them to complete those asks either way. Limit Epic requests to weekends and it would be fine.
