Power leveling and Level Sync

Personally I do not feel Power leveling blue mage is or should be considered an exploit.


Here is why:

Without being able to queue for instances, and especially without being able to party with friends of higher level (due to lack of level sync for open world party content outside of FATEs) Blue mage is restricted even further.

Blue Mage also is not a solo job, as the RNG for actions in level 50 content is extremely low if blue mages had to go into a full blue party (which is not solo still) it would take even longer to farm the actions.


TLDR
So how is power leveling an exploit, without level sync being an option to party with friends, and party'ing with level 70's to farm Pharos Sirius (as just one example) not an exploit?


Suggested solution:

Either buff BLU so that its a solo class, add party level sync, or allow BLU to queue.




NOTE:
I leveled Blue Mage normally and took it from 1-50 in about 8 hours using my chocobo companion and party'ing with friends/randoms.
