From what I've seen typically most popular (sometimes even full Zeal if you're able to ignore 100% defense or close through bonuses, etc.) on Trunda in Hydra. I think I've seen a few other champs/builds but can't recall, unfortunately.

Like Thorne said, the endgamers are certainly using it.  That level of gearing is beyond my pay grade.

I have a couple of champs with just 2 pieces based on optimizer recommendations.

Same .. and for handful that still had og Crit Damage I swapped out for short term fix rather than fully re-gearing. 

Back to the original question:  Has anyone seen anything testing it agaist Lethal or Merciless in terms of Damage potential?  

I have collected 18 pieces I deem good enough to keep, but have not used any of it yet.  Wouldn't mind clearing that space if it isn't OP; however, @xonak makes a solid point.  I could clear out all OG CD gear first.  Coincidentally, I am sitting on 18 pieces of that as well.

It is just so hard for me to dump 6* Lego & Mythical gear that is already rolled to L16 with good stats. Some of you are way better at gear cleansing than me, but how do you just sell a piece like this:

That's a useable broken set peice, especially since it ascended speed.

Well let me ask this, do you have a few 50s or 60s sitting in the vault you never use and haven't geared? If there's any lvl 16 gear I'm concerned about tossing, I try to put it on a Vault champion like them. Usually there's space on someone. Especially now that I'm using the HH Optimizer so much. It's good just to have somewhere that it can use to calculate what I'm attempting 

Definitely a good suggestion. 

However, at 34M Player Power, I can't even keep track of all the unused gear stashed on (mostly) unused epics, and every time I want to clear the high-end stages in Sintranos that require gear chnage, I have to clear my calendar to handle all the gear moving I need to do....
