There is no reason why when doing leve's in a party and you D/C you should not be able to rejoin the leve once you log back in and still get the same SP/EXP per mob. As it is now when you D/C you join back and have lost all the link's, your GA and everything. This happened to me on Dunesfolk a few days ago after the first set of Mongrels, I went from getting 1238 SP to getting around 200 SP a kill. That is ridiculous the system knows how many people linked the leve as everyone else still gets the same SP so why can't it remember you when you rejoin the leve?
