Ok so Lets assume everyone here goes and joins an FC and finds a static, etc, and they no longer pug. How do you expect the people who wants to *have fun* to clear the content they wanna clear and not self improve?. Fights like Titan are unclearable if people have too many deaths atm, you won't make the dps check no matter how over geared you are, and if you're not dead but you're a BLM doing only 6k and your other DPS can't compensate because they're equally underperforming how do they clear, where is the fun in wiping for several pulls and not getting past phase 1 in hades?
At that point they're not even running savage or EX anymore, they can't see past phase 1 and every competent player is no longer pugging because as you said, they shouldn't play with theese people. You now have several issues to deal with not only as a community, but SE as a developer and Yoshi P as the lead of this game, people can't clear and they'll say the game is too hard, vs the real issue people needing to improve. Like it or not, simply telling people to *not play with others* will change nothing.
As per only *getting 300 extra dps* no in a lot of cases is very staggering how many pugs underperform at the baseline, people should be able to at least manage 10k flat and barely do that. If people learned they're rotations they can see up to 14-16k if not more with proper alignment and knowledge of the classes you have in any given run. The lack of this knowledge and people such as yourself refusing it is why from 5.0-5.1, the content has been fairly dumbed down, Yoshi P himself wanted to make Titania EX harder, and guess what he had to NOT do that for the sake of people not being able to actually perform.
In the end, I will repeat to drive this point home, If people in this community want to get rid of ACT so bad, Improve, Theres no Ifs, and, ors, buts, just Improve. If thats not for you, stay away from Save and EX, there plenty of other optional content for people to do that requires no competentcy.
