maybe its just me...but is leveling too fast in your opinion?

Not if SE were to nerf the EXP one can receive while under Lv.Sync.

And then nobody will want to use it.

The purpose of level sync for me is so I can level my lower level classes due to the lack of players, playing with friends and other LS members is a bonus, so yea I would most likely not use level sync if it has this kind of restriction.
