I mean ultimately, even in a game that is 'combat heavy', I would say even 2 or 3 quality combat sequences per rest is more than your average DnD tabletop campaign, unless you're just running something really kill heavy. Additionally, from a role playing perspective, I think it would make sense that the large majority of characters would want to engage in life or death situations as little as possible, and especially when it isn't necessary for some tangible objective. For those that truly feel that murder is an important part of progression, then the value provided in the loot, or in not having to parlay with those you encounter seems sufficient enough.
