it's always been about fighting. i mean even in castlevania 1 simon had enemies that took 6-8 hits, and you weren't getting past them any other way. forced fighting you could say might be a problem of the 3d games. walk into a room only to be forced to clear it out. works for zelda, but seems off for this series.
up until the qte's and puzzles i actually would agree with making it more like god of war. it'd have to have it's own system, naturally. belmonts are tough, but they can't rip their enemies in half or slam giant columns on top of them. however it would definitely be sweet if they had more stuff like, say in that one stage in the first god of war, where you had to jump onto platforms while avoiding saws and falling into the chasm.
