No. it can be easily abused to get legendary primals just by clearing GR 1 or 2. you can powerlevel tour character, then do the GR, get, primal, and repeat.
RNG is rng. Got my lvl 70 GR primal AND primal from Kadala gamble right after. Better RNG than I have experienced in all other seasons so far. RNG is rng just saying.
Had something similar happen several seasons ago. I ran 2 sets of bounties early in the season, like maybe a day after hitting 70. Decided to roll just for an ancient Yang’s and got a primal on the second roll. Slapped in a DML and only three rolls later, it was primal too. The Yang’s was perfect, but the DML had a couple of bad affixes but still, was a pretty good quiver considering how early in the season I received it.
First rule of being a troll is you don’t get to decide who is a troll. Troll is only something non trolls can decide. Heck I will even settle on actual D3 players being able to decide that.
My GR70 Primal this season was Raiment Boots. Since I use the Raiment 4 Inna 6 Bounty build, I’ll use it. At least it wasn’t an instant salvage as other season’s GR70 Primals have been (Razor Stop, Non Immortality Follower relic, Leoric’s Signet, etc.)
