Mythic BFD

So me and a few guildies are thinking about going back and doing the previous tiers Mythics (at least Uldir + BFD), for some Mog, Titles, and Potentially the mount.. There's roughly ~13 of us - and we plan to pug the rest - but we are all geared and in the (465+) range, and have killed Heroic Nzoth and all that.

Has anyone gone back - and recleared BFD? If so - how hard was it, do you have any links for updated strats ( strats that 8.3 players can use - not ones developed when it was current? Are there any pieces of advice you can give? We plan to re-read up on all the fights, and "Raid" it semi-hard, but any help would be greatly appreciated!

Thanks!
