I'll third was Tobias and Packetdancer say. That's a lot of premature negativity for never having tackled the content and you are judging something and the people currently doing it without really having tried it.
I agree that this game has a really strange difficulty curve. Throughout the MSQ you have mostly extremely faceroll solo duties duties, then comes the odd spike that catches you off-guard and requires slightly more attention than "press any button to win" and back to facerolling. Same with the trials. Most are extremely easy but then you have the occasional trial that still trips up DF to this day like Titania or WoL.
Normal raids usually don't have any form of dps check, you can just keep throwing bodies at the boss until it eventually dies (that 14min e4n run I had being one such example). No mechanics that wipe the raid when messed up, barely any mechanics that one shot you when messing up.
While the confusion of "what's going on here?" may seem like insurmountable difficulty if it's your first tier it's in truth just a matter of getting used to a different overall encounter design. I also played WoW and it took a tier for me to really understand how endgame content here works; that's normal.
And you can get away with a lot of deaths in Savage. I had the messiest kills with deaths and mess ups on several mechanics. The only guaranteed wipe mechanic in p2s is if the dps or tank with the debuff stays in the group and yeets everyone else into the wall. No way to recover that. But deaths/ mess ups on numbers or arrows are recoverable more often than not. Gear helps a lot here with making the dps check or taking harder hits e.g. during Coherence from missing people.
And PF right now is filled with helpers. It's not all "only bad raiders are left" doom and gloom, many really good players are bored out of their minds because their static steamrolls these fights on Tuesdays so they hop into PF and teach people fights. And it's extremely effective. Most "practice from [one of the first mechanics]" groups turned out to be a kill party with only one or two other helpers.
Some mechanics are memes in PF like p3s add phase or p4s Pinax but that doesn't mean you'll be hitting a wall and be unable to clear until next expansion. You'll wipe to it a couple of times, someone may leave or get replaced and try again but it's rare to see a party not getting past the meme mechanic within the evening.
If you are interested in raiding there's nothing except your own mindset keeping you from doing it. Saying that you need a static, that you'll be helpless to progress if PF isn't at their best game, that you'll spend weeks on a boss for little to no reward is simply wrong and unneccessary doom and gloom. And definitely not fair to all the people out there constantly teaching and helping with clears or people that simply started later but are quite capable of learning.
