I apologize as I don't have much to recommend in the solo front, the only solos I've done so far have been Pallad Percy
for RDM seals on RDM/DRK, and anything in La Thiene that I can drag to a pinning spot. Koghatu
has been eating up all my time lately, he's soloable on RDM, but haven't attempted it on BLM since I like to hide behind Utsusemi and it's just too hard to recover from a mistake on BLM. The strategy for him is pretty easy, pop with sneak up, run him over to Conflux 7, and run him around in big circles between the conflux and the big rock at the top of the ramp. He TPs 3 times in a row, so I usually get hit with one, then trigger the next two by letting him get just
close enough and running out of range. This is where recovery on BLM isn't as easy since you can't just throw up Utsu. He basically only takes damage from fire spells, and triggering !!
can be pretty frustrating, but there's a martello you can hit up right on the kite path so MP usually isn't an issue.
I hung out in the zone and offered to help people that were spawning the Shiva VNM and picked up 6 BLM Body seals one day.
Then there's those domination ops, I spammed a ton of the Buffalo and the Dolls in Vunkerl but you are looking at a low occurrence of any of the 10 different seals dropping each time you complete one. The bonus here is that if you hang out long enough, a party will likely happen and it's easy to get invited, in which case you could be completing a Domination Op once every couple minutes.
That's really all the progress I've made, and appreciate any other solo/duo info I can get.
