Unchained, when do I use it?

The way I do it is I make a choice. After my opener, I very rarely need to actually use Butcher's Block - the threat you gain from popping all your offensive buffs with Maim and Eye up pretty much seals your hate against everyone. Eventually I might have to BB, in which case I'll usually just let Path fall off for those few GCDs and then go back to SE -> SP -> repeat.

If damage is more valuable than the mitigation (aka any content where my healer's aren't stressed for healing), I'll drop SP entirely and just SE -> BB -> repeat. But usually this is just 4man dungeons and stuff, I value SP pretty heavily for any 8man stuff.

This also sorta assumes you've got a decent enough weapon to keep hate against the DPS. The worse your weapon, the more times you'll have to BB. You also might not be able to get away with opening with Eye if your weapon isn't up to par, as you're generating enmity solely through damage and offensive buffs - no enmity multipliers involved. If that's the case, you should open with BB -> Eye -> BB. Unfortunately that's the worst of the two options, but it's not something you can fix unless you get a better weapon.
