IIRC so there is very little point to partying up for her if don't kill Spite Wardens.
Unless there is a new cheese strat for wardens that I dont know about, no fetter VD run is slightly more efficient IMO.
If you do no warden run with BLM, and each run takes 2 min, 4x2=8, it takes 8 min to complete 4 runs for 4 drop slots.
Even if getting KI takes 2 min, getting 3 more KI to retry only takes 6 more min for 14 min total.
In other words, unless you can kill all 3 wardens in VD in less than 14 min, or theres a long wait between each try, you arent beating no fetter run in terms of efficiency.
Never mind the fact that in BLM setup only RUN, SCH, BLM amd GEO needs to be geared and have playing skill, the other 2 people can just be a roll *** and TH *** that just sits there spamming absorb TP.
In other words, in BLM setup you can find any 2 people for last 2 slots as long as they can spam absorb TP. They can be people needing different drops, or nice people that just wants to help, or your mules, whatever.
In a warden kill run the other 5 people has to be well geared players that you would invite to difficult content, then you have to hope they need different pieces.
If you 4 box BLM setup should be far easier to pull off since GEO SCH BLM can be automated quite easily. Then all you need to do is finding 2 other leechs that needs different pieces.
