I get less SP from leves, this is true.

However I also haven't gotten used to the CON/THM changes yet and haven't partied up for them either. There's also more ways to gain SP for DoW/DoM now (Dungeons and quests) and I've noticed better SP gains off mob grinding (150-300 per mob as opposed to 120 every mob prior to the patch).

I don't think it's too bad. I ranked up twice today in the 2 hours I played by doing leves and grinding :3
