When you think "triumph" you think something [u]achieved[/u] by hard work and alot of effort. When you think "RnG" you think [u]received[/u] by a luck factor. SO the idea of putting a requirement on a Triumph that is a RNG based item that is also timegated so you cannot work hard to get it.... well lets say there is neither logic nor common sense in it. So all we can do is look for alternative reasons to do something like that. First i thought it was to create a hype and addiction effect on said item. But mayority will just get frustrated and annoyed, acomplishing the opposite. People don't complain a lot these days, they simply move on, so that would be a bad gaming-development strategy. Than i thought it might be to slow down progress. That makes most sense to me, make them waste time so they stay hooked on the game, chasing that elusive item. You see that coming back alot in destiny2. Loading times to the tower are horrible, yet every quest makes you go there after completing a step or 2, some even after every step. Recuiring trajectory medals for mountain top? doesn't count the ones you already had, doesn't count in Iron Banner... delay tactics. Chasing some competitive PvP quest, lets go back to orbit every time instead of Crucible match selection screen. Creating an economy to infuse armore and weapons... to make it meaningfull? no, it's to make you waste time. Make players waste time with deleting 380 gear, blue gear, double exotics, shaders, going back and forth to the tower for bounties, etc etc. all to make you waste time. These may seem minor, till you add the time spent on deleting them.. then it's hours, days, years. Most of it is simple to fix if they wanted to spare you time and frustration.
