I hadn't played for about 9 months or so and I've gotta say they've updated it quite a bit, skilling is alot easier now, both level at the same time regardless of which skills you're using. as salio said , FB got a new BM2, FS got 3 new skills, 2 aggro drawing and an Attack + buff. There's a couple new dungeons(depending how long you've not played) LiD, RS and EoD seem to have been nerfed, they're extremely easy now, but the exp is the same. A few higher level basic crafting things have been added including High slot extenders, I've noticed a huge drop in bots (again, idk how long you've been gone, this is a view as a change from 8 or 9 months ago) that's about all I can think of that's been changed.
