Personally I farmed my legendary through tunnel farming and WvW, precurser was a random drop from a temple.
A good 3rd of the items you need you get along the way doing 100% map and explorable stuff (pre drop nerf).
And while you do get sick of seeing the same skins over and over again, after farming mine (Incinerator, don’t even really like the skin) it was purely for my own sence of achievement.
I tend to play my necro more than thief so it was never about showing off.
There are alot of players though I can say would have CC busted to get one, which is stupid but to each thier own.
More skins would be nice, and won’t really bother to get my second dagger until they have alternate legendary skins.
