Because I don't understand. Here's my particular quandry. People like to say, "Well, running full exotics would be OP!" But that then begs the question... How is it that every other MMO/RPG that I can fathom has NOT had this arbitrary limit and yet the end-game content is still difficult as heck? Prime example, Borderlands 2. Borderlands 2 allows you to put every epically amazing gun and shield and such on your character all at once. These guns can be utterly ridiculous, shooting all four bullet damage "types" at once, ricocheting sniper shots that leave shock trails, rocket launchers that home and fragment and rain down fiery death on your enemies, just all sorts of amazing ridiculous things. And there's no limit. And yet, Borderlands 2's (that's an awkward phrase) endgame content is some of the toughest stuff I've played through in a game. You feel powerful, and yet you can get smacked down by an angry mob or a ridiculously tough boss and have to use all of your considerable character skills and weaponry to overcome it. Let's look at World of Warcraft. The whole point of that game is to constantly get better and better gear, and again there's no limit on the best gear you can take. And yet the end-game content is still incredibly difficult (although I use that kind of relatively since WoW keeps getting easier and easier with every patch and expansion, but I digress). So clearly, given the precedent set by every other MMO/RPG that I can think of, it's entirely possible to allow a character to equip super insane gear and yet still find great challenge in the late-game bosses and arenas. That officially defuses the "it would be OP" argument. It wouldn't be. Unless you want to admit the end-game is poorly designed, in which case bad design COULD lead to weapons being OP. But barring that, you're no longer allowed to use that argument. Again, to recap, every other MMO/RPG does NOT limit your super-gear and yet they still maintain challenge in the end. The other argument I get a lot is, "Well, it makes you make choices about your playstyle." Now I have to disagree with this on a few points. First of all, this is a video game. Why do we all want our video games to be so deep and about choices. There are plenty of games that do that, plenty of GOOD games already out there that do that. And they're fun in their own right. HOWEVER, this game's ENTIRE goal is to become super powerful, and yet it is handicapping itself by saying, "Look at all this amazing stuff you COULD be wearing, but you can only use one!" That seems to defeat the overall purpose. Second, it actually ends up limiting your playstyle instead of truly expanding it. Yes, I could switch gear in mission or between missions. However you run into a few problems. The biggest is that it can take anywhere from 10-30 seconds for the darn menu to load. Yes, I've had it take 30 seconds to load, I timed it. That means you really can't do any switching in battle that would add any strategic value. Either you'll be dead, your team will be dead, or the battle will be over. With any of those choices, you have to remove yourself from the fight to do it. Now what about switching between missions? Well that's all well and good, but it's still limiting the options I have at my disposal. I go from locking myself into one particular playstyle, into locking myself into another. That doesn't really change the problem. Let's say I have a chestpiece that gives me boosts to heavy ammo and grenade count, allowing me to dish out damage decently well. And let's say I have a headpiece that allows me to revive teammates quicker, but I'm not wearing it because of the arbitrary limit. Now it's the end of the third wave on (insert any strike name here) and my teammates all just got clobbered and I have only a short period to get them up. If I had both exotics equipped I'd be able to run in and use the quick revive functionality (thereby opening my playstyle to allow me to support in a time of need) whereas otherwise I'd have to hide from the battle, switch out my chestpiece, switchout my helmet, hope I don't get killed in the minute of downtime it took to load the menu and make the switch, run around to revive my teammates and then repeat the process again if I want to keep dealing damage. Or run immediately into the fray playing subpar and likely getting killed and having to restart or get kicked to orbit. Arbitarily limiting choices does not expand replay value. It doesn't. You want us to craft our own stories, Bungie? You want us to feel powerful? Then LET us. I'm entirely fine with limits in PvP (although I think Iron Banner would be hilarious with full exotic loadouts), but someone REALLY has to justify this PvE limitation. Think it'd be OP? No other game has had that issue. Think it creates replayability? It only frustrates and slows-down gameplay while limiting options in combat. I don't get it. PLEASE Bungie, PLEASE let me be the badass I want to be. It's the light I've been clinging to for this game. It would make my time seem so much more worth the effort, like I'm actually getting rewarded for my efforts instead of being scolded and told to pick only one piece of candy. Choices are cute, but this game isn't about choice, I thought it was about being the strongest gaurdian you could be to fend off the incessant onslaught of four powerful alien races! You really think you'd be limiting your soldiers for that? Really, it wouldn't be fair to fight off the legions of enemies with really powerful gear so we have to do it with one arm behind our back?
