If you don't get the complaint, then don't try to because you won't have any idea of the kind of built up frustration that a lot of people feel over this kind of issue. Its not just DA:I either in my opinion. Many PC gamers have to deal with dumbed down limited controls on SO many games these days. When it happens to a game that you REALLY care about, especially when its from a series that was originally designed for a PC, it hits hard.
Its kind of the "straw the broke the camel's back" scenario. So unless you have had to struggle through interfaces in dozens of games because they were poorly ported from a design/control scheme that lacked even the basic functionality you are used to having then you probably can't imagine the built up frustration about this issue.
Its just one of those painful issues that comes along with cross-platform development. I am not sure how great of an analogy I could create to explain the situation either.
Ok, my attempt at an analogy:
Imagine you go to the movies often, and you always sit in big comfy seats and everyones quiet. You enjoy a large popcorn and drink for every film and you love it the experience. Then one day, the theatre decides that they can make a lot more money by removing a few seats and making people stand. Over the years, you notice they remove more and more seats. Then one day on the premiere of your FAVORITE movie sequel, you go to the theatre hoping for a good seat of the few that remain. There are no seats anymore, the soda has been watered down, the popcorn is stale, and there are a ton of people standing room only talking away while your film plays. The people who had NEVER before been to a theatre with seats tell you that they don't quite understand why you are upset. No theatre they have ever been to has had chairs before.
Ok, that's probably not even close... but I am tired.
