Guardian Rank, all things considered, can be a nice way to softly tutorial people through the game by making them do specific things through various activities. However, I think the loot grind associated with it is a little high with the current rate of progression for most people. i think putting T4-5 loot in GR 8 instead of 9 but keeping the need to be able to do GM diff would be better then making people lose their mind power grinding to 400 to just barely be able to do that. getting to 400 and being GR 9 is such a drag and a needlessly long process. considering that people would need to still increase their light level when they play solo anyway but being able to play with your friends that are higher light to help you get better gear would be a MUCH friendlier system than right now. tiered loot aside, fireteam ops should either be 2 reward base or similar to how pinnacle ops does its rewards so it'll give 1-2 rewards based on how long or quick the strikes/missions can be completed in. overall it doesn't feel as rewarding to do them if were only getting one drop per run when there is literally solo ops being done in half or even a third of the time and more rewards per hour. it cant be that hard to balance the time investment and rewards
