I don't see how someone can be a BG fan and not have liked the BG combat system. That combat system is integral to why those games were so awesome and to the way they felt and played.
The more I learn about Larian's plans for this game, the more pessimistic and disillusioned I am becoming. First they talked about cutting back on misses in combat and possibly even dropping the to-hit mechanism. Now they're talking about easier and faster leveling, and getting rid of spell slots. I feel this is going to be just another D:OS game pretending to be a D&D/BG game, complete with the very boring and superficial D:OS combat system.
