I'm confused as to why the pet jobs specifically are in such dire need of this. If it's so important that people have access to TH2, then shouldn't it be every class, not specifically half the ones you play.

Also, the idea pet classes "gimp" themselves subbing Thief is absurd. None of the pet classes have difficulty subbing Thief. Dragoon is the only one where a different subjob would make a big difference on soloing capability.

Also, if you truly don't have time to sit around farming low drop rate items, there are lots of alternatives that are guaranteed drops or earned through simple repeated tasks. No, they aren't the best items in the game, but it's a little absurd to treat the super-rare items as somehow being mandatory. Outside the content where you try to get super-rare items, there isn't any real requirement for them, so if you don't have time to do the content where you need those items, which is where you get those items, then you can ignore them.
