I don't remember every single detail of everything everyone posts in here, pardon me.
I also never said it was impossible. What I was saying was that, as @The Stranger put it, "a bunch of shitters who do crap damage and think iLvl will save them from enrage" is essentially par for the course when it comes to PFs. "Putting your nose to the grindstone" with regards to that proves my point, the "grindstone" in this case being having to jump through Lord knows how many shitty parties to find the one party that can clear.
I sure as shit wasn't able to find that attempting my own Valigarmanda EX progs. What I did get were retarded healers who kept fucking up the last stretch of the soak phases during the middle phase with the tank swaps, tanks who kept fucking up the tank swap and, for some reason, were allergic to popping their panic button mitigation (seriously, it's ridiculous how often I had to directly tank two or three bursts solo using my own mit because the other tank was either late to swapping or ate shit from insufficient mit), and generally retarded parties that, for the life of them, couldn't figure out how to split and soak the AoEs during beacon adds, and this was with having pre-established groups before attempts. Also, shotcallers being absolutely retarded with RMMR placements (these idiots CONSISTENTLY kept trying to basically make the two separate groups mix and match each other's members for RMMR instead of just, you know, one group does their own RM positions, the other group does their own MR positions, easy peasy).
Actually, on that note, one group actually kicked a guy OUT for telling people correctly what to do and pointing out specifically who was fucking up where because "Dude learning party, let us learn lol, why you getting so mad lmao".
