all i am saying narisa is that grind parties and pl parties should get the same amount of sp. i haven't said in here that is should be removed. as i have stated many times it can be done either of 4 ways.
1. increase the rate of sp for grind parties to match the sp of pl parties.
2. decrease the rate of sp for pl parties to match the sp of grind parties.
3. do both by increasing the grind parties sp and slightly lower the pl parties so they are even.
4. put in a level sync so even if you invite a high level character into your party they can help a group without doing all the work for them.
either of those options leaves the choice for someone to enter either type of party. as it sits now you either get in a pl party or you do not get into a party.
