[0.3] Fun Wall Vaulting "Combo" (Whirling Slash + Shield Wall + Disengage) build

So, I've made a build that revolves around this neat little "combo", which is the synergy between Whirling Slash + Shield Wall + Disengage.

The build itself can take many forms, mine, for example, is physical with emphasis on heavy stun, armour break and armour stacking, but it can also be a bleed (since it have two big hits) or an elemental build to make use of the infusion mechanic of whirlwinds.

The interaction between skills is simple, but also more than meets the eyes. You use whirling slash three times to build the max whirlwind stages for the high collapse damage, place a shield wall, and detonate both with disengage, which allows you to cancel the shield wall animation a bit quicker than usual (thanks to the innate "This skill can be used while using other skills" effect), thus reducing the time window where you're vulnerable to attacks and effects like stun.

The full combo motion brings many utilities to the table: You're almost always moving thanks to whirling slash forward motion. You detonate two big nukes, which are the stage three whirlwind collapse plus the shield wall for very high burst damage, and have the option to vault forward or backward, depending where you point your mouse while using disengage. Disengage also works as a superior dodge, since it "causes Strikes and Projectiles to miss you while jumping.", and doesn't slow you down at its end.

Overall a strong - not overpowered though - and, most importantly, FUN combo, which could be the bread and butter of many spear and shield builds, so it is quite versatile.

CAUTION: May cause or intensify carpal tunnel syndrome.

Hope Jonathan is proud of this combo! The VISION LIVES!
