Timers remain a staple of the game, however I do feel some could be reduced.
Certain weps shouldn't take 24 hours to create, 12 is enough, match it with the rest of the weapons, or atleast cap it at 18 hours, if said weapons use parts that themselves need time to craft, then the end-goal weapon should also be reduced. (6 hours on weapon part, 6 hours on weapon craft)

I personally wish Forma/Potatoes also take 18 hours. (Although I guess if DE reduced it to this amount, people would be likely asking for a further reduction, so shrug.)
Frames should take 2 days tho, to account for the Warframe component craft time.
