Dual speccing in the SAME AC is not changing class, it's changing roles for people who rolled Advanced Classes that can tank heal and DPS. DERP!
Love it when you people bring the only, vague and pathetic card you have to play in this idiotic little crusade of yours - choice. So what, we go with your idea of choice? Ooops, I experimented too much with my class and now the respec cost is too high, time to reroll the same class, but it's ok cause choices need to matter?
And how does dual speccing affect that? Are you sure you understand what dual speccing even means? You play one spec no matter what, you use your tanking spec, you have the pros and cons of a tank, you choose your DPS spec, same thing. What the **** is the difference? Oh yes, I don't have to drain my credits on respeccing constantly if I want to tank and DPS, SEPARATELY using an advanced class that accomodates both. Nice logic there man.
