Maybe some people find DM boring to watch, due to all of the item gathering. Is there anything enjoyable about watching people run around a map and collect items? The fighting and killing is what people want to see.

As a solution, the item-gathering system could be replaced by a regeneration system. Health, armor, weapons and ammo could all generate and regenerate. For example, the game could cap your rocket ammo at three. Rockets regenerate at 1 per 2 seconds. That means, you would be unable to really spam them, and depending on the health and armor of your opponent, you may need to use more than just rockets to get a kill. Additionally, you could make it so that some weapons are not available throughout the entire game. Like, the railgun could only be active for the last five minutes.

With the (re)generation system, the game becomes about managing your items as opposed to running around collecting them.
