Duelle this thread is about making multiple forms of gaining SP/EXP and the only way that can be achieved for Grind Parties to become viable is to remove the cap. If everything was fine as is then there would be grind parties everywhere but there is not and this cap is one of the reasons for that.

Now if you do not like Grind Parties then that is fine this thread is about supporting other ideas that allow for other ways to gain SP/EXP and you should look into those. My preferred way would be to have Grind Parties as one of the options and the easiest way to achieve that would be to remove the cap along with other adjustments. The other way to do it would be to buff mobs a lot so that a mob that was the same rank as you would actually be an even match and a challenge, that would make something that is 10 ranks above you impossible to kill solo and would require a party to do so. Obviously further adjustments to SP/EXP would be needed to make this happen but I feel as though this way while I would prefer this way it would anger a lot more people.
