I'd like there to be a checkbox on the skill merchant window. If checked, skill merchant display would be as it is now, showing both those skills the merchant would normally offer and all those skills the character has unlocked on this account as well. If unchecked, only those skills the merchant would offer by default would be visible.
This would be helpful in a number of ways. For those of us that like to play multiple characters of the same class it allows us to have that "first time through" experience with the class again. For veterans helping out new players it would allow them to see what skill the new players have access to at a given skill vendor with ease. And best of all, since it's just a check box (and on would be the default, presumably) it in no way affects those that simply want to ignore it.
I know that for myself and several other players I've spoken with this simple change would make the game much more enjoyable and much more replayable.
A similar check box in the skill window for heroes would just be gravy.
