Unchained, when do I use it?

[Krissey]

Unfortunately that's the worst of the two options, but it's not something you can fix unless you get a better weapon.

I bought an illvl 115 Axe from a vendor in Ishgarde when I dinged 50 immediately, just in case you are refering to my ilvl 90 Bravura. I am doing the relic quest for fun, because it is the iconic Warrior weapon from the artwork and I want to take it to maximum glowy/spell effects without changing it into the double bladed axe where it loses the recognizable iconic form. So I think I'll be stopping at Nexus, which will probably be better than the vendor axe of equal ilvl i bought.
