Motes are what you need 300 of to go from the heroic weapon to the legendary weapon. Its not for faction, which im already at max faction (over 12k)
You get 5 motes per named
or 5 motes for a t1 armor piece
10 for a t2
or 15 for a t3
I just need to find a 3 dot or something named on a 20 min timer
Oh yes, it was a while since i was there. I seem to remember most of the motes came from turning in unwanted Armour pieces, and hitting the named mobs in drake riders.
Some of the outside ruins have named pops but there place holder spawns.
