Onslaught should get buffed.

[Rhyn]

Onslaught doesn't need to be turned into a clone of the other tank's gap closer. It should work exactly how it does now, except for the following changes:

Make Onslaught usable from outside combat, for free. While in combat it costs 20 gauge.
It now triggers an 8 second eye buff. This 8 second window has three functions:
- Fits an Overpower/Mythril Tempest rotation, which further extends the buff, making this a nice way to engage a group of enemies.
- Fits the 3x GCDs you normally need to apply eye, meaning you get the damage buff for your initial rotation.
- Doesn't allow spamming of Onslaught as a replacement for doing the eye combo. This is why it's not 10 seconds.

Onslaught vs. Fell Cleave as a gauge dump is pretty similar now, so the damage per gauge is in a good place.

With these changes it is now a really thematic way to initiate combat for a warrior. You can always use it, and charging into the enemy is really warriory and will feel so much smoother than not being able to charge while OOC like now. It also solves the issue WAR has atm with having to build up the eye combo when AoEing packs.
