Don't think like that.. try this way. This is a hard server, you have to farm a LOT and probably you're bored, so you think to do some pvp/pk but wait.. YOU CAN'T! because you don't want to lose 10% that means an hour or more of leveling in medium levels, but... there you have the Death's Deal Certificate 50% for 1 day. So now.. at least you will save the half exp, on 10 deaths of a day of full pvp/pk you will save half level, and that time, on this levels, could be 8 hours of leveling, thats worth for me.
