Speaking for myself, I don't like having to hit various key/button combinations, particularly if you have to match timing as well.
In Evil Islands you could hold specific keys down while attacking to target specific parts of the body (ie you have a lower chance to successfully hit someone in the head, but if you do it does much more damage), or simply attack and the game would choose (primarily targeting the main body). This could be very useful against strong opponents especially if you could sneak up behind them, but most of the time I didn't bother.
If different attacks could be set up something like that, then that would be fine. If fights would need to be micro-managed or require lost of key mashing that would turn me off the game completely.
