1. Most gap-closers aren't used to open a fight (i.e. to "engage"). Engage skills are meant to decrease the time between when the tank first pulls and when everyone else first hits. A tank teleporting to the enemy is counterintuitive, and slightly decreases the raid DPS dealt over the duration of the fight.

2. If Onslaught cost TP, yet Warrior TP were infinite, it would effectively cost nothing. Even if their TP were not "infinite", it would still remain free damage obliged to be used on cooldown, thereby hampering Warrior's freedom of movement.

3. Onslaught IS a DPS gain in certain circumstances. Apart from those it is only a slightest DPS loss, even if you exclude the bonus to uptime it can bring (which can very well give DPS by using it as... a gap closer). The skill is incredibly well balanced for a low-CD gap closer that doesn't oblige you to use it on cooldown (thereby wasting its purpose as a gap closer). There is scarcely a better tuned ability in this game than Onslaught.
