I do agree very much so with not wanting to fight the same mob over and over level after level.
I do believe this will all work itself out and SE will adjust SP to a more normalized and even level.
in a party fighting harder mobs I would believe 250-300 SP/fight would be fair.
and solo anything from 130-200 sp/fight keeps it fun and paces things accordingly. Add in if they can slow the gear damage that would be fantastical :)
