So, i am playing with my friends, and everytime we try and do something, for example a pinnacle ops (any other activity as well) my guardian power remains the same. I play with 2 friends, one of them has 438 power or something around that, while the other has like 312, while i have like 368. The problem is that whenever a fireteam starts an activity it usually brings everyone on the highest power on the team -5, but this doesn't apply to me, beacuse when i start an activity, with these two guys, my power remains the same, preventing me from doing like master difficulties, while my friend with 312 power has 0 problems, and his power just automatically boosts to 433, while i stay at 368. Does someone know how to fix this?
