Setsuai, you can find maybe 1-2 other people for skill ups at Boyahda or Zeruhm Mines. Also check these GoV areas, some people are doing magian trial where they have to kill 250 rabbit or mandy, which makes it easy to just cast paralyze, slow, dia, blind over and over or do lower tier nuke (or sub blm for frost, choke, etc - can also do helix). These soloers will greatly appreciate what your SCH can bring - safety in numbers - not to mention you help them kill faster. As for 6 person party - it's pretty dead, but not 2-3 people killing decent/even match mob at GoV. For example, the typical crawler nest party is near the entrance, but further in you can do the crawler/beetle one at the beetle camp. No one hardly there and easily duo up to level 63 before xp is dead. This is good to duo skill ups from 58-63 skill levels (up to 200s). As always you can speed it up using some food that will get you faster skill ups gain.
As scholar you can also offer them skillchain partner to finish their weapon skill trial or mythic weapon skill trial. Actually this is probably your greatest asset and you should freely advertise this in your LS. Many people need to skill ups, doing WS trials, magian trials, etc. Having a mage is a big plus - and outside abyssea, sch and rdm are very capable to self sustain and never run out of mp.
The game has many options now but you know, the general public will always follow the hordes. The good thing you only need 1-2 other people to hit the GoV page skill ups. As for people running around in peptobismol gears, they may not have time to seal farm or have no idea on how to do the abyssea content properly other than lvlng up via dominion
