I am an altoholic and have several characters of the same class but with different looks. Obviously, I am not keen on grinding extra 400 points on the same class for each class multiple times; it says nothing about ‘mastering’ a spec, it’s just an anti-alt grind wall.
So my suggestion is: once finished for the first time, the elite spec should either be free to train on other character, or cost just as much as the base specs.
20 level 80s and counting.
