I'm just gonna start off in my usual fashion by calling you what you clearly are...an idiot. There is no such thing as a "casual" or "competitive" gamer. A game being competitive is purely a state of mind. ANY game can be competitive so long as the participants at the moment, are feeling and or dedicating themselves to making said a battle of whits or skill. This may be a shocker to you, but not everyone plays competitive 100% of the time.
And do me a favor, show me some statistical data to back up the claim that these "competitive" players earn the developers and publishers more money. Seriously, if your gonna throw claims like that around, show me some revenue reports or statistics directly from Microsoft, and some half baked argument about what you have seen personally.
Also sprint has been a feature in a LOT of games over the past 30 years. Maybe not in the sense of what we are used to, but the condition of speeding up the players movements is a long and used mechanic in gaming. Sprint does have a place in Halo and it is not a forced mechanic on ANYONE. We do have custom options and playlists, but again, whether or not those playlists are used or created is not the developers concern.
And real quick,(i had to edit this) please show me some data also that indicates that a majority, that being 51% or more...since you probably aren't very good with numbers, of players do not like sprint, and believe that it does not belong? Because coming here or a handful of other sites is NOT gauging the entire communities perspective. unless your seriously going to to go around and collect actual names (separate site and member) and poll answers, you CANNOT legitimately claim that a majority of players hate sprint.
Quick scoping is not a skill. I've seen my son do quick scoping with one eye. The fact that auto-aim and aim assist exists by default, make quick scoping or any other form of it on the console a complete joke. Now on the PC....completely different story.
