Side quests and main scenario quests also give SP now....
A lot of SP in the case of main scenario quests
Also.... They have yet to rebalance the MOB distribution fully... but we have been told that will be done to accommodate more leveling parties with the camps needed to grind if you choose...
We've also been told more world beastmen and beast strongholds are coming in one of the next patches (I wanna say 1.19 but I can't quote that for sure) which should make leveling a heck of a lot easier seeing how Amal'jaa for instance are in the top SP tier in the game. So world grinding Beast MOBs or storming beast strongholds should be just what the doctor ordered
Yoshi P admitted there would be a dip in SP gains between 1.18's guildleve change and the redist. of MOBs
