Even in regular MMOs you tend to get sucked into fights that you didn't intend to start. Think of aggressive camps along the way or enemy players in PVP servers. You can always find the "safe" routes which are usually paved, that would at least save you from the wrath of aggressive camps.
Also, most of the turn-based games implement a very lengthy fighting style with little "motion" into them. I personally liked the way Paper Mario: Thousand Years Door Fighting style. There's a lot more action you can do in its fights than regular games that I've seen in my lifespan.
Another thing I'd like to mention is that making the fights more rewarding for the time spent would make a lot of sense. A fight that lasts for, lets say a few minutes, should definitely be more rewarding than doing a 30 seconds of mashing buttons against your macros.
One last thing to add, there should be the option to escape fights with a certain way for making it fail. If you escape a fight it would be nice if you get tossed a short distance that would allow you to move away from the fight.
