So instead of talent switching, we'll have class load out switching, which is really just the same thing.
You'll then need a macro that swaps your main class, sub class abilities to another main class, another sub class abilities, and also switch out the weapons and armor for both setups. If the UI is customizable, you'll likely need different addons for the newly switched to class combo too.
Additionally, no longer are we talking about just inventory management, but class management and class skill management.
SOUNDS EXCITING.
