Overall i'm extremely happy with how good melee is here. I'm getting consistent 11 kills per hour at 500% at around 4:30~ average outside of some super lucky sub 4:20's or super unlucky kills that go like high 4:40's

Pad order 2-1-4-6-5-3

Important things regarding some pads;

First pad(Pad number 2) I do take dba on every kill on mages for first pad because it makes the skip impossible to fail and it helps me get the grey hp down to near zero in zerk rotation.
I don't charge pad as i'm waiting for zamorak to come melee distance, instead i'm standing behind the pad for zamorak to get over melee distance which he does while you do your first three abilities and on your fourth one(barge) it is always in perfect position for you to start throwing hands with him.
Rotation; Zerk - divert - preparation - barge - roar - overpower - assault(DoT Barge effect) - destroy(fully channeled) - dragon claws - dragon claws - greater fury - dragon claws - havoc - leng spec. Leng spec goes on last tick and so many dragon claws almost assures you will get some shards for extra damage :)

Second pad(Pad number 1) This one i will always zgs to save time. Thanks to the dba allowing me to get the grey hp all the way down to near zero on first pad which gives me incredible consistency in getting this pad mechanic skipped without zerk. I will always run on the same tile right next to the tiny pillar at the edge of the pad(1:35), while i'm running from first pad i tend to resonance to gain some hp back and then i will do any other defensive that keeps me still to get adrenalin. Then i barge - zgs spec - cleave - assault(DoT Barge effect) -Overpower(important cause it starts refilling your adrenaline immediately so you can squeeze in dragon claws) - greater fury - dragon claws - dragon claws - dragon claws and it's phased and the rest is just improv. I usually spend my primordial shards for leng spec here, my goal is to get grey hp down to 80k~ before i head to kill the mage.

Third pad(pad number 4) From here thanks to cooldown reduction from the first pad(pad number 2) i'm able to zerk on every edict. I will always bleed flurry while i'm on zerk and i will continue to do this till i'm on the last pad(pad number 6) where i will bleed assault for the extra damage.

Phase 7. In phase 7 i try to get my hp down low and the first rune i try to finish off with greater fury, so that while i'm running towards the second run and i'm doing my freedom and devotion. Once i barge on the rune it's instantly killed because of the guaranteed crit and i can safely just bladed dive next to the boss and instantly bleed assault - overpower - dragon claws - leng spec and it very very often dies before you even get hit by the bomb.
Sometimes what happens is when you enter p7(4:40) and you target cycle, it cycles on the god damn rune on your left side and if you get the same rune as your first, it's going to die on first basic because of it's low hp from the barge and that's the only time you can't quite finish it off with gfury so you might have to use another basic on the second rune just to make sure it dies.
