Zekvir Heroic Tips for Enhancement?

Title won’t take ??, is for hard mode, FYI.

My Enhancement set basically is my Resto set with Champion track weapons and terrible trinkets. I took the talent to clear the spittle with ghost wolf. I find it extremely difficult to delete the cocoon if Zek drops it clear across the room. I saw some players mention baiting the frontal, but I can’t afford that time. If I don’t switch to the cocoon immediately, I just don’t have enough burst to kill it. I build up to a tempest on Zek and hold it for the cocoon. I burn Ascendance or Doom Winds/Feral Spirits when needed, but the third time he dumps the cocoon clear across the room means both of those are unavailable.

He seems to tend to pop it in the corners to either side of the raised platform, so when I move over there, he’ll either frontal (which is sometimes manageable) or fear (which means I get screwed since I usually get stuck on the corner of the platform.

I’ve gotten to the second phase twice. The first time, I didn’t notice a swirly while desperately trying to delete the cocoon after he did the usual thing of tossing it clear across the room. The second time, I got swallowed by a portal (spawned right on top of the cocoon) and tossed around the room while spittle depleted my health bar. How is a melee class supposed to clear the cocoon and avoid the portals, especially if that portal gets dropped on top of the cocoon?

I have over 250 attempts on this jerk. I’m getting RNGd to death, either by maelstrom simply not building, or by cocoons that get placed too far away from my current position. Brann also doesn’t switch to the cocoon half the time, and he tosses his stupid vials far away from me. He’s useless.

I can one-shot the normal difficulty now, so it’s not like I don’t know what I’m doing. I have a Wind Shear macro to target Zek to interrupt the heals. In ??, I get 2-shot by a crit either immediately following a hit for 1.5 mil, or the other way round. I have Amorphous and Porcelain Arrow on for the majority of my attempts. I went with Sentience and Earthmother for a few, but had even more trouble with the cocoons.

Any tips for Enhancement?
