Looking only from technical perspective, microservices are worse than monolith almost every way you can measure. The biggest benefit of microservice architecture is that it handles multiple teams better than modular monolith. This is good enough rationale if you want to have team independence and clear separation of responsibilities and you can accept all technical problems microservices bring. If you cannot accept such problems (like in case many desktop apps and at least in some part of WoW backend) you just need to select something that will work with your constraints - usually it is modular monolith architecture, sometimes something more exotic.
