I FINALLY got the P3S kill yesterday, my pain has come to an end xD.
Basically a whole week of endless suffering and people having no clue, the group I cleared it with was a last desperate attempt at 3AM.
They needed a physical ranged and I actually wanted someone else to join I was sitting there waiting for a while for it to fill up so I could have an excuse to go to sleep instead.
I was VERY close to not joining, after waiting for a while I just clicked join and I had the urge immediately to leave I was just so done with it and tired both actually sleepy and also tired of pf.
In the last group before that it was a kill group too where the party leader said they'd kick people for repeated mistakes, and the the leader proceeded to make mistakes every pull themselves...

It took like 4 attempts and on the first attempt we wiped to enrage at 0.2%, the other dps in the group were wiping and taking damage down on a lot of stuff.
On the kill pull it was the same thing too and we had to lb3 ress because all the other 3 dps died ( and someone died before that too I think )´.
And it was so close I thought it'd register the enrage again, I've seen that happen before where the HP reaches 0% but it's the very second the enrage finishes casting and it counts as a wipe it was one of those moments but the RNG gods were on my side.
Except for the chest rolls I guess lol, in P2S I rolled 4 and 5 and my usual 20-30 rolls.
In P3S I rolled 20-30 on everything per usual again it's like a curse I have.
I ain't even mad with those rolls after an entire week of pain, I am just so happy it's over.

Even if Duty Completed groups aren't perfect it's at least not on this level.
I've never felt so defeated by something in a game before but the moment when it finally went down felt really good too I feel like I can finally relax.
