Make a Third Talent Specialization?

Q u o t e:
GC already commented on this and the answer was no. Maybe down the road.

This is true.

We want the game to be more fun by making it less painful to switch and play multiple aspects of the game, but we still want some decision-making and deliberation to be involved when building your character. If you had tri-specs, or even quad-specs, then talent builds would become less meaningful and choices would become trivial.

We like that you have to make some choices on how to specialize and adapt your character, and we do not wish to change this by removing the need to respec when trying out new things or changing things up a bit.

You can probably gather from this that we have no plans to allow for a third talent spec, and it will be a long time, if ever, before we would consider such plans.
