I mean I barely played Reach so I may sound like a total newb here and have to remove this post. It's not something that I was especially looking at and then beta was over. I'm too lazy to watch videos. Can anyone comment?
My rant is, that single wield weapons makes the game way more balanced and way more professional. A dual wield vs. single wield doesn't prove the more skilled player. It only proves who was luckier in finding the doubles or spawning in a lucky place.
To summarize, I just wish that it was single wield only in Halo Reach multiplayer but I know that is just a dream and nothing more.
