Ok this is my 1st time posting a thread and im reasonably new to this forum or forms in general frankly so excuse me if this topic has already been discussed elsewhere.

I frankly do not understand the XP/SP system of this game. I have been putting considerable effort recently into putting together to the best of my abilities FF11-style grind parties to frankly limited success because the party search function is frankly a joke. (won't harp on that anymore here) and I've taken severl parties to the same camp and for the 1st time ive partied enough to notice something strange.......
The number of people in a party does not really seem to have ANY effect on how much xp you get per kill. I had a group of 5 ppl killing beastmen for about 300 or so SP/kill and as people started to leave the kills inevitably became harder and longer but the sp stayed at EXACTLY what it had been prior. Eventually it just got down to me soloing and it took me like literally 10 minutes to kill one mob and STILL i got the same 300sp/kill. I was stunned to make this discovery......... Doesn't it make sense for the amount of comparative effort involved in killing something to have a reasonable effect on the amount of XP you get? Is this just some kind of strange bug I ran across or is this how this games system is actually supposed to work? and if so please someone help me understand the virtue of it.
