I like to really be taking in completely by a game, have as much control over the character as possible.
I've played my share of mmo's and in the department of combat they seriously lack, I can eat, drink something etc whilst in mid combat. The mechanics of click a monster and you start attacking it just doesn't do it for me as far as combat goes. On the other hand the Diablo trademark 'click click click click click click click clickity clickclick' is just as mind-numbing. TES Dark Messiah beeing and 1st person action RPG was a pleasant tho short experience where it felt like I really was in control of combat instead of rolling dice every second.
So I'm not into overly complex combat systems, a simple system that still gives me control over every action is IMO the way to go.
I don't believe gameplay mechanics should suffer from the limitations of the roots of the genre, that meaning that RPG's rolling the dice was a limitation since you had to fantasize this all and rules had to be set to make it enjoyable. Or I would have just used my special attack to one-shot every mob I encounter. A PC or Console game takes away a lot of the imagination but it does give you the chance to have the combat more depend on more than just stats & odds.
