Hard Mode Vorkath with Melee Camp? (RS3)

Not efficient or clean at all, but ... a kill is a kill?
This is not the first time I have killed him with melee in hard mode, however previous attempts were just slower due to it being difficult to reasonably defeat Vorkath and minions that are hard hitting.
I figured that if I don't have a reasonable way to dps Vorkath safely in phase 3, I would try just focusing effort damaging Zemouregal - much like the normal mode skips. Running to the far edge of the arena is just an attempt to lure him so that I don't have to really run far away from the ice breath or around poison pools. This is basically a crude attempt at stalling with spirit shield camping and using defensives while keeping a blood reaver alive with a prism of restoration. It is probably better to just go around and kill off as many of the harder hitting minions as possible to reduce total incoming damage since it seemed rather painful. (I was kind of just building on Zemouregal and ignoring them for some time ... which they did pile up)
My expectation would be with good damage rolls and/or prebuilding before each Vorkath flight - a 2-cycle could be plausible and save much more time. Interestingly, he's not completely immune while shielded at this phase, and damage eventually added up to finishing him shortly before Vorkath flew again.
I did panic a little at the end because I was trying to dive out of the way of a bone spike but ended up clicking on the extra action button instead and tanking the hit - oops!
There's definitely room for improvement like not fumbling of necklace swaps such as chaos roar into dclaws instead of ek-zekkil (forgot to swap after first flight zerk ended), as well as making sure to keep prayer points up.
Using devotion and having it extend from killing minions right around the start of berserk can potentially save from an untimely finger of death during the rotation (this actually happened on the second flight zerk where it looked like devotion extended from a minion dying right before finger of death came out)
Side note: I am intentionally not using greater bone shield and darkness just to see how it goes without them. (it would likely go much smoother with darkness)

With blood reaver anything is possible. lol. I hope they nerf it. I will say, I really like the concept of just killing zemo and killing minions/damage zemo. I feel like this is a cool concept of a boss. It's the closest thing to an endurance/wave boss, where you need to kill the minions and survive/mitigate damage and then burst the boss.
