Soloing is totally an option. A lot of pages give quite nice exp and jugs, especially the newer ones, hammer out high damage against lower leveled targets. The changes in monster distribution may have also opened up some neat opportunities for charmed familiar play. And since Familiar is now on a one hour timer instead of two, you can have a familiar up half-time, which is also neat.
If you want to solo, go for it, but if you want to say catch up with people, maybe get a new LS or something, consider checking out one of the current main spots for alliance leveling:
(All ranges approximate)
Gusgen: 15 to 35
Crawler's Nest: 35 to 60
B. Oubliette: 60 till cap
Keep in mind, however, that the 95 limit break does require a group currently.

When it comes to sitting around not doing anything for long periods of time, only being active for short windows, and marginal changes and sidegrades I'd say FFXI players were the perfect choice for politicians.
