Yeah, they waste a lot of great looking designs on rare gear plus the finite amount of legendary gear leads to a lot of look-a-likes throughout the game. For example the warlock chest pieces available through the vendors are beyond ugly so everyone is starting to sport the Chasm of Yuul. However I don't believe morphing rare items into legendary's would be the best solution to avoid this. I would like to have a base armor underneath my guardians "clothes" that would have a talent tree similar to our supers, but have the unlocking path be different. Instead of XP unlocking perks have them unlocked through specific activities or quests. There would also be exotic perks, but you could only use one at a time. I am well aware this idea could complicate the light level and would certainly make exotic, or rather all, gear irrelevant for anything other than aesthetics. Which, to me, would be amazing.
