Hmm grabbing the attention of an enemy as an off-tank. Legit I can dig it. As a dragoon wouldn't a simple jump suffice though?

Building TP faster, im sure is a great tactic, but how is that at all fair to archers?
While archers build TP only on their light shot (Assuming your not autoattacking)
Other class can just straight up auto attack and throw in the extra tomahawk for more TP?
How is that fair?
