With trash pull with tomahawk, then overpower and main combo( HS->SK->BB) using flash after SK. After this continue to rotate main combo between enemies(and use overpower sometimes), checking sometimes the enmity bar. And yes, try to keep up maim always, it's a huge dmg/enmity buff, so why not using it? Cooldown wise, Foresight and Bloodbath have a short recast time (90 secs) but they aren't that strong(especcialy Foresight), use them with trash to mitigate a little bit of damage and recover some HP. Cast Berserk (possibly with Bloodbath, but use Bloodbath first, then wait 10 secs and use Berserk, so you will not waste 5 seconds of Bloodbath with pacification). Use the stun too, it gives you 5 seconds of reduced damage(a stunned enemie can't obv attack), so it's quite useful. About Defiance, use it ALWAYS, you can only switch it off with when you are finishing a weak enemy, so you can kill it faster.
