10% of ur current progress for feeder class

so if u have rank 5 and 70% to rank 6 and u die, u'll lose 7% and go back to 63%.

i think its +1% punishment for each higher class. so 11% lost for samu, 12% for pala, 13% for monk and so on.
would be nice if someone, who did tests, or from experience, can vouch this.
