I'm waiting to have a max AP of 12 before going to the Iqhan caves or over the the Prim/BWM side of the collapsed mine.
Edit (3/23): Got to level 24 and used my skill point on Cleave, and had a change of plans on waiting for Combat Speed 2 before going past the collapsed mine to do the Prim and Blackwater Mountain quests. If I was able to do it my first game with 10AP, I should be ok, especially with skills and equipment I didn't have before (Regeneration, Corpse Eater, Cleave, critical hit gear if I want to switch to a build using the Villain's blade, etc.). So far so good.
I'm planning to make this character as "good" as possible, based on what I already know about the quests. But in some cases I don't think either side is more good or evil than the other.
Saving up for the Jewel of Fallhaven took a while too, but thanks to Regeneration and Corpse Eater, I wasn't as reliant on meat and health potions (regular or minor) so I was able to sell off more of those than when I first played through and there wasn't a skill system.
So far its been pretty fun going through it all from the beginning but this time with the skill system in place. I imagine a new game might be more difficult after the next update because the critical hit system was going to be revised so that its not as powerful, and I relied on that for a few of the quests after I had the venomous dagger and then Flagstone's pride.
At the level I'm at now, I've found the Izthiel bridges to be a good place to grind for XP - generally around 175 which is more than the Gargoyle trainers and masters, and you get more gold selling the rings they drop compared to the ruby gems. And 100 gold for every 20 Izthiel claw sold to the merchant in that trading post.
