The assets pipeline can be tricky, sure, but it&#x27;s tackling an issue that is really hard to get right. Routing in Rails on the other hand, I don&#x27;t really see what&#x27;s so complicated about it. You define resources, you have namespaces, constraints, the DSL is extremely nice and straightforward, I think it&#x27;s actually one of the huge successes of Rails as a framework.
