Thats the thing, I would rather have longer games than a dozen short ones. Makes the game feel all that more epic that way. A good 15-30 minute long fight makes it feel like you accomplished something epic instead of 3-4 short MLG games that blow by so fast its almost like whats the point. Keep in mind this is my opinion, not actual fact.
It also depends greatly on the map. Some maps are suited to close quarters and others not so much. Both benefit however from having an active motion tracker.
More to the point, if a player chooses to camp then thats the players perogative. It has nothing to do with any mechanics in the game. A motion tracker being on or off wouldnt matter as the player themself is chosing how to play the game. So in a sense I just think people should get used to the idea of a motion tracker being there. Most people, I find, ignore it anyways so its not too big of a deal. Players will play the game however they wish to play it reguardless of how the screen is set up, motion tracker or no.
That is where this stems from. People want others to conform to their own playstyle, which I think is wrong. People should play the game however they wish (as long as it is not breaking the games fundimental rules, such as glitching or hacking). Competition is still plenty strong and people would enjoy it just as much if not more because of the freedom it gives them.
