Blizzard for BFA had player level 111 BOE epics which were basicaly level 120 starter epics and previous legion expac had player level 101 equip BOE epics that were basicaly 110 starter epics.
both expacs had unique scaling, where you had 101's boosting players to 110, in BFA it got even worse with 111's not only level boosting players to 120's, destroying 120's in WPVP, also carrying 120s thru dailies, islands, expeditions, etc. until the nerf where grouping with a XP off player vastly reduces your XP.
i wonder if blizz will repeat the above a third time, with early level BOE epics at level 51 or 5#?
