Okay, you asked the question, so I'll give my [b]THEORETICAL[/b] answer. This system is designed to reinforce the rules set in place with the introduction of a single power weapon. With the introduction of only one extremely powerful weapon instead of two, players will be forced to choose one and adapt to the role that weapon plays in combat. If you have a look at the power weapons, they are all mostly situational. Snipers are useful at very long range, shotguns are useful at very short range, fusion rifles are useful in controlled situations in which you have time to charge shots, grenade launchers are useful for clearing ads, etc. So players are forced to pick combat roles, and specialize in these roles. Imagine a raid in which the two best marksmen in the fire team are designated snipers, the most agile player takes in a shotgun, the player who likes to clear ads takes in a grenade launcher, and one flex player takes in a fusion rifle. Obviously the raid design (assuming this mechanic is in play during the raid) would have to change to accommodate this set of roles. This may allow pve players to focus on what they enjoy to do, and get very good at a particular role, enabling a sense of individuality and mastery. This locked load out system could be in place to make people choose their roles more wisely. Now everyone, put down the pitchforks, everything here is totally theory, and was said in part because I think a system of role would be cool. I do not think this system is necessarily the best way to approach this issue, but it looks like the locked load outs mechanic is gonna be something major. Edit: oh never mind, this mechanic doesn't apply to raids. Well hey, this theory could still apply to Trials...
