I know, I know - - I suppose I'm just a purist or something.
First of all I don't like that annoying pause when I arrive at a new area (it's like the game thinks it's in multiplayer mode and I can't seem to turn that off). Also I enjoy the unity of the single storyline in SoA, and I like to use the low-level spells more - with ToB, the enemies (which you HAVE to fight, can't bypass them like SoA) are SO raging that the only spells they can't seem to save against are the killer spells (Dragon'sBreath, ADHW, ProjectImage, etc) - so it was a little bit one-dimensional for me... Plus the questing in ToB was more linear than SoA, where you could wander through Chapters 2-5.
[BTW, where do we draw the line between SoA and ToB anyway? Seems like a lot of cross-talk so to speak between the two forums...]
Anyway, to get back to the topic, I will have to try Valygar again to make sure a sextuple backstab wasn't a bug; this time I'll try to get a screenshot for proof of the damage numbers
