Yeah the reason you have drops that are only t2 it's because of your guardian rank.. There are tons of research about the expansion that clearly states that it's not just about your power has to be at a certain point to get higher tiers you also have to be a higher guardian rank because bungie repurposed The Guardian rank system to be more of a purpose to have a reasoned to be a guardian rank 8 or 9. Example if you look at arms week if you look at the weapons from the event page it literally says the Max is T4 but it depends on your guardian rank... Logically this would apply to trials because trials is an event but it's also part of the portal and people already said that the items from the portal your rewards are based on your power level and based on your rank... The only way you could get a T4 without a high rank is if you do mystic weekly story missions on kepler... Also I would really avoid pvp right now it's a mess it's unbalanced it's filled with nothing but cheaters and hackers and you're damaging players and they're walking through walls it's out of control even streamers before the expansion said bet the cheaters in the crucible are spreading like a wildfire.. Like for real think about what happened with world's first bungee said 70% of people in the community who did the contest mode for the raid they cheated... They didn't banned these players but they labeled them as cheaters in the community.. I guess that's what they do now if you cheat or hack you don't get banned you just get labeled and you get like a Pat on your back 😆
