I mean of course It's great that Xbox has a whole platform built and layed out for us with support and what not and not seeing hackers is great.
I think he realized it without saying he did.
The problem with what you are saying is that many of the people who have been grounded in Xbox with the controller as the main thing to use since they had the 360, is that it's not okay to have controllers mixed with KB&M. It's not okay for me to be facing a 5 man team and my team is using controllers and they are using KB&M xim 4's. Thats childish, pathetic, and really not right. How such a low % of people see this as an issue blows me away. Xbox shouldn't let Xbox fans with more than 10 years played on an Xbox just get up and leave. They need to appeal to the audience that has created what is Xbox today.
They are a separate system for a reason and regardless of personal bias and whatever Xbox is doing currently, it is not right to be putting up Mouse and Keyboard against Controller users in ANY competitive or even casual circumstance regardless of beliefs. It is up to the developers and Xbox to take a stand against unfair use.
Whether you are match making or people exploit by using emulators, it needs to be used in the correct manner for games like MOBA, FPS, and MMO, and Fighting games specifically. Which those 4 categories should be using controllers only. Especially since it's optimized specifically for Xbox One.
