Trainer-only Skills...

Just a little thing. Since GW:Factions is so new and there's very little information about skills' locations etc. I'm wondering if they should perhaps introduce some kind of "key" for the skill-traders to let people know which skills are trader-only and which skills they'll be able to acquire through questing.

In the mean time, anyone know if Gash is a trainer-only skill?

In Factions, if you don't get it in the first series of quests from your initial profession trainers, you have to buy it. Factions doesn't have the quests with skills as rewards, like Prophecies.
