I am sorry, but I think that Arenanet is again extremely disconsiderate towards its players with disabilities. To have such an important thing in game as the skyscale mount "puzzle-gated" is horrible.
Don't get me wrong, I used to enjoy puzzles. But once my hands stopped functioning normally, I can't do them anymore. The easy ones, it's ok, I manage to get through them after a few times, but the harder ones I just had to give up. It was ok, I still was able to enjoy everything else.
It's frustrating enough that I can't do things in real life anymore, and Guild Wars is my virtual escape, where I can still run and do things. I went through the list and steps of getting my skyscale fairly nicely until I got to the "lost Skyscale" collection.
You really should think about your players. Give us another way to get it, even buy it, I don't care. I know I'm not the only one here who has issues like this.
And before you start commenting "omg stop griefing just because you suck at puzzles", yes, I suck at puzzles, and can't get better at them, I can only get worse at them with the degenerating disease I have. I shouldn't be punished for something i didn't ask for. I played Guild Wars since it first came out, then Guild Wars 2. It was practically the only thing that kept me sane while I was going through cancer treatment. No, I don't want to go play another game with no puzzles.
Seriously, can't you make it so people who are disabled can enjoy this too?
