Have you done COG Gear? I’ve only played as him a bit but am interested in finding out other people’s builds and views on how to best use him/her, especially given the OP 4 changes.
EDIT:
I checked just now and you have, although his was back in November 2019.
If you’re revisiting characters to include updates then COG Gear, but if a new character I guess Paduk. You’ve covered most of them now I think.
Maybe you could do a list of characters you’ve done (and in which operation)? Would make it easier to decide. Because I’m basically not interested in any guides that were made pre-OP4. 
Good point,
For OP4. There is Keegan and Clayton.
So the space is there to redo some old ones.
I’ll add this to the original post as well.
Cheers!
Then it’s definitely Paduk that I’d like to see
Yes Paduk Hulk !!
Thanks for you experience sharing 
Paduk, please hulk really appreciate the time and very helpful Guides,many thanks
You don’t.
I vote for Paduk please 
It’ll be good to see how many cards we disagree on for the fear build 
Show me how to make Kat relevant…please.
Hey Slip,
Will see where the vote goes. But I can still show you in game some time if you like.
Cheers!
I vote for Keegan.
I really love your character guides! Looking forward to the next guide regardless of which character ends up winning the poll!
You’ll be pleased to know that Keegan was covered quite recently, so all of it is up to date!
Or show us how Grace is relevant to us! 
Ur guides are super helpful man im voting for Paduk guide or Cole
Thanks Warden,
I appreciate that.
I’m voting for Cog Gear man. Maybe more people would be willing to use my horde main if someone they respect would hash out his many abilities for them.
Paduk would be cool to see. I would love to see your take on him since he has many different playstyles (sniper, executioner Fear based, hybrid, Fear shotgun man, mid range Markza DPS you name it)
Thank you,
Not sure of the respect part but I do try and help where I can. 
Cheers!
Closing as per OP request,
Can’t wait to see the guide
