I have a very reasonable and in my opinion , very helpful idea that could possibly be implemented in an update. Soo my idea ... Here's an example where it could help , ............. ..... . How many times have you been at the final challenge, so close to defeating atheon. you see the very unforgiving 30 second timer for times vengeance , you have equipped your *insert exotic primary* you have used to destroy supplicants and you want to switch to let's say, your mighty gjallahorn , but by the time you've gone to inventory and swapped the weapons , you have a minuscule amount of time left and probably only get one shot off.Tragic.... . So I impose bungie should add a d-pad controlled quick weapon swap system . Let's say click up to change your primary , left for secondary , and down for heavy. You could also possibly add right to change subclass?? . This would save vital seconds as you could do it with out going to the inventory screen and wasting time , and instead you could click up to scroll to a non exotic primary then down to scroll through until you reach your exotic heavy. Please help save a time deprived guardian today.
