It's okay to have a power advantage, it was okay In Destiny 1. The artifact needs to have its power turned off in crucible (Iron banner/Trials of Osiris) it creates a huge disadvantage for players that don't play destiny 7 days a week for 10 hours a day. It was horrible this last Iron banner when every other game has a power level 999 Grindtard taking a deuce on everyone because he/she doesn't have a life
