[quote]Not sure if this is something I’ve missed all this time, but is it ever explained why we can only equip 1 Exotic weapon and armour piece?[/quote] I’m not aware of any lore-related rationale explaining why characters in Universe are unable to equip multiple Exotics, however… [quote]Obviously, it’s to stop us being even more powerful[/quote] The two reasons previously cited by the devs for why players should never expect to be able to equip multiple Exotic armor pieces simultaneously (even for limited time, inconsequential events) derive from technical limitations of the game engine upon which Destiny 2 was built, namely: A) Exotic armor pieces are generally more graphically complex than their Legendary counterparts and thus take more processing resources to display in game. Allowing players to equip multiple Exotics simultaneously would therefore lead to more frequent issues with poor performance in higher player-count activities (6v6 PvP, the Tower) especially for those playing on less powerful hardware. B) The game engine is really only capable of keeping track of so many active effects (between Perks, Mods, Exotic effects, Subclass Fragments, buffs/debuffs and Activity modifiers) before major systems start to break down and “bad things” happen. Because of the way in which major mechanics are fundamentally tied to the underlying code of the game engine, there is no realistic way to improve/alter [i]certain[/i] aspects of the game without a time-consuming and expensive set of updates to the engine itself. This would be a difficult enough ask for a game at the height of it’s popularity and profitability; given the series of setbacks this dev team has experienced over the past few years, it would be irresponsible for them to attempt such a overhaul at this time.

Sentient exotics probably get jealous if you try to equip others.

Lore-wise, probably not so much. There are two Felwinter Warlock exotics which probably indicates he wore them simultaneously and Osiris looks like he is wearing about 3 of them if you count ornaments: Dawn Chorus/Sunbracers/Lunafaction Boots. Our canonical Guardian is powerful but technically we are more of an anomaly rather than being stronger than our NPC counterparts. Osiris couldn't account for us in his simulations, Elsie didn't have any changes to her multiverse trip until she met us, both the Emissary and Savathun hinted at our ability with the 4th wall, etc.

It's just a game mechanic. Lore wise, there is no limit to exotic usage, and ability/super cooldowns vary between guardians (for example, because of Ikora's studys on the light, she can be seen using multiple supers in a row)
