I don’t think the problem is as much that there aren’t enough skins available from gameplay, but there aren’t enough specific enemies that drop specific skins. I mean, I remember going into Sorrow’s Furnace in the first GW and farming certain bosses for a specific skin and it felt so much more rewarding when you got what you were looking for.
As it stands now, it feels like there’s no real aim for any farming and good item drops are just something that happen randomly with no rhyme or reason.
This isn’t true, as the gw2 equivalent of Uniques are associated with enemies. However there is a great deal of randomness and a god-awful paucity of information on what exotics drop from what.
Here’s some examples:
1. Say you want a Flame weapon. Where do you hunt for it? It’s a Charr cultural weapon, so you find them in Ascalon. What drops it? Just about anything if you’re above level 34 – it’s a common Rare.
2. You see someone holding a kittening scythe, called Final Rest. Where do you get it? From the only critter that has it: the Shadow Behemoth.
3. Here’s a tougher one, and a cool one. Lord Taerne’s Shadow. What drops it? Chances are good, if you have one, you took it off of a Champion Spider.
4. The horrible looking greatsword Crystal Guardian – where would you get this? You look for a Branded champ.
4. You want to make a Corrupted Weapon, but that requires a lot of luck in finding a level 80 Etched weapon to start it. Where should you be hunting for it? I’ll let you guess this one.
