So close to being able to solo farm those damn bird mounts, but not quite.
You can solo all of them I believe, although Nidhogg is cancer iirc. I think for some of them BLU is faster than a 80 unsynced too, because Basic Instinct is so strong. Still overall faster to just party for them though, a lot die in like 2mins or less in a party so you can get your mounts at fairly good speeds. Obviously you often get groups with shitters that take longer(especially when it's DPS sensitive tasks like doing the Byakko skip and ppl are so fucking bad they somehow can't do it with i510+) but for the birds at least it shouldn't be a problem anymore unless it's like 6/8 glue tasters.
There's an incentive to hook up with a larger guild that maintains FC buffs, especially while leveling and at the start of xpacs. Even if it's a horde looking for warm bodies 10-15% goes a ways.
If you're new yeah, but if you're not, you should be saving up on those scrolls from the weekly GC squadron mission, you get 10scrolls that last 2hours each and give you lvl 3 FC buffs equivalent for most of them(not rez sickness or + craft/gather skills, but all the xp stuff, longer food, higher spiritibinding, higher MGP) and they stack so you can run a bunch together if for some reason you want to.
You should do that a couple of times at least before the expansion and then you're good for a fair amount of time, and obviously you can keep doing it, I have like 60 of each or so and I use them for whatever, haven't used xp ones in a while since I'm capped other than BLU, but I did use the food duration ones when I was doing this savage tier. The scrolls are lvl 3 too which most FCs don't run unless it's expansion launch(and even then) cause it costs a bunch of old mats to make the wheels to generate the buff and stocking them up is some treasure hunt map level of garbage.
I made my own FC too though cause I figured I didn't really care about joining random ones, so I have those buffs if I want them. Got to rank 8(for the lvl 2 buffs) in like 4 or 5 days of turning in expert deliveries from shit I was rolling while farming my relic(especially the 18/18 24man step). That said the buffs are expensive to use as a solo user so I've just been letting it build up for the next expansion so far. It's a free FC chest though which is nice.
