After getting RDM to 90, I set about leveling several subjobs and other main job interests. In doing so, I have found a way to provide a symbiotic service to my Gusgen Mines GoV party. I level sync for them while I go to work. So long as they don't let me become the leader so that I have to be phased out, I sit there gaining 10~15 EXP per kill while they make upwards of 1300 every six kills. I act as a perpetual sync that doesn't need to be changed. As I leech my way up through the upper 10's and lower 20's, my party can vault themselves upwards into the 40s and 50s. It's no problem for me, as around 25, I become active again and fight up to around 35 at which point I can go to Crawler's Nest.

I understand that some are opposed to this style of play, but I hate levelling through the 15~25 range, so it is mutually beneficial. Everybody wins.

What do you think? For? Against? Why?
