For me Unchained is used only once. As an opener, tomahawk, the bb combo, the blade debuff combo (eye or path, I'm at work and ill, help a guy out XD ) at that point I have 4 stacks, pop internal release, berserk, unchained and do bb combo till pacify. I do that to get an amazing hate lead to swap into my dps stance and use that. I will say this, I only do that in boss fights I know very well otherwise I don't touch unchained. To me it's a tool to be used at certain times like all of the WARs ability's. I can't think of one thing that WAR has that I never use (least used award goes to the dps aoe attack you can use at 5 stacks, forgot what it was but yea, very rare it's used)
