I agree skill, even the map bosses weren't even that exciting. You could just attack a big mob with 3 areas to hit and not just one. That's it. The Zhaitan boss battle was just horrible. That whole quest needs to be scrapped and completely redone because its just a complete anticlimax. The mouth of Zhaitan you battle before attacking Zhaitan directly was harder and had more interesting combat than killing Zhaitan himself, that's just sad.

I actually found some of the explorable dungeons to be challenging though. But when you find ways around the boss' attacks then it just becomes repetitive and almost grind-y once again. In AC i spent 15 minutes just constantly dodging and attacking one boss in one same algorithm, very very boring.
