Bullshit. Also, apologism 101.
DA:O's combat sucked because it was scripted as fuck (in a very bad way), and the combat itself was a clusterfuck built around insta-stunning abilities that really dragged the momentum of encounters down, stupid MMORPG mechanics such as aggro, shared inventory, "complex" spreadsheet design (read: big, meaningless numbers à la 574.3 dps against a 2581.2 hp monster, how long will it last LOL), and a myriad of other bad things such as bad item design (particularly unimaginative use of damage type), class restrictions and abilities, monster types (undead? demons? just like orcs LOL), etc.
So no, combat in DA:O was terribad and only gullible dumbfucks think of it as 'deep and 'complex'.
