[WoW] Keymap performance issue?

Yeah the key in the keymap, say key1 does have a step in it that turns it back off. That step is usually 2 or 3. Depending on what I need first. Like turning on the burst keymap and turning off the normal rotation keymap. Or changing a step in a non-iterative key somewhere.

The usual usage though is:

Key1 - Step 1 - Activate something, deactivate something else. For x seconds and only once.
Key1 - Step 2 - Activate something else, deactivate something. Turn off Key1.
