Almost every class has a useless skill. Paladins have Divine Aura and Brute Force, Warriors have Restore, Mages have Frostbite, and I'm sure Rogues and Archers have one or two abilities that no one uses (feel free to post which ones below). I think STS should either replace these skills with more useful ones, or at least fix the problem with the current skill. That way, people could tweak their character to fit the playstyle and tactics they prefer using, instead of dumping points into the same skills everyone else uses.
