While they are adding this feature, they should have leveling dungeons (atleast HW and SB content) also be locked behind ilevel. I was tanking two groups yesterday, in the first Stormblood dungeon and the Vault. In the first Stormblood dungeon both DPS were wearing level 56 gear. The dungeon run took forever and it wasnt untill I inspected them that I noticed their gear. In the Vault the healer had issues healing, even with facing only a boss. I checked her gear at the end of the dungeon run and saw that she has level 20 accessories, level 50 gear and a level 47 weapon. I understand being undegeared for 5 levels, but having 20 levels lower gear or 40 levels lower items is insane. There needs to be a gate.
