How can we actually know someones level besides inviting them to a group? I am surprised there isn't a mechanic so you can lock onto other players & see their level beside their name as most MMO's have. We can only make an estimation by inspecting their gear.
Their level? Anyway, inspecting them doesn't give you an estiamtion, it exactly shows you their level.
When you inspect someone, it shows their level and mentor right under their body model. You talk about inspecting gear and such but how could you have missed this????
