I don't think there needs to be any additional content added to the town. Here's why:
There's plenty to do inside and out of Cyseal without it. Adding it at this stage could make it seem forced. This is the first town we have gotten to see. If they add a battle or two to Cyseal then they will have to add that many to every town in an attempt to keep it balanced. So say there are 4 major towns you are now asking for anywhere from 4 to 8 additional battles to take place. The reason I say this is if you add it to Cyseal and not to others then the comments will be "Why only in Cyseal? Why aren't there battles in [insert city name here]?"
Also, stating that completing the quests by fighting isn't your playstyle so they should add combat so it can be your playstyle is kind of off to me. Because what about those who want to not have to worry about random battle XYZ happening in town when all they want is to walk to the market and buy a heal potion? That additional content you want may not be THEIR playstyle and now you have forced it on them.
If the added battles are (as suggested) under a statue, or well, or somewhere not implicitly tied to the main quests (it's own area to explore and gain quests) is the best option.
