I would say it's be smart about it. I use Ansible quite a bit. When I first started, based on some examples I found, my play books were pretty complicated, with a lot of conditional steps, doing things (or not) based on results of previous steps, etc. What I found is that it's a lot easier to have a lot of roles that each do one little thing, and then use them in a play book as needed. A role might be as simple as installing a package, templating a configuration file, or maybe even just changing just one line in a config file. When roles are small and do just one thing, they are easy to combine in many different ways, and it's more obvious what's going on.
