Removing the ability to PF savage is one of the worst things you can do here. The problem with pugs is that there are absolutely 0, and I mean 0, standards of play established in this game. People are allowed to join content and not know anything about their job and often times don't get punished for it. Damage meters occasionally become toxic because there are players WATCHING people with 0 knowledge on their job completely throw the fight while understanding they can't do anything about it without risking being banned. SE needs to establish standards of play for savage level difficulty if we want to see any type of improvement in the pug raiding scene, this applies to EX content as well. The fact that 0 damage healers still exist in this game in SAVAGE CONTENT (or even EX content and lower) is a testament to why this is a problem and that it NEEDS to be addressed. I get this is a casual game but the players that have absolutely no interest in learning anything about their jobs past an extremely basic level (especially if they don't even learn the basics) should not be allowed to access Savage content without a full 8 man premade, period. Running into players that can't play their jobs at a basic level is extremely frustrating and really takes away from the experience, especially when those same players are toxic and shuffle blame towards others.
My point is pugging savage isn't necessarily the problem. If players at minimum could do average damage and could do mechanics semi-consistently, PF wouldn't be all that bad. Right now, you have players that do significantly less than average damage and can't do mechanics consistently at all. Removing the ability to pug savage with less than an 8 man premade only punishes players that don't have a consistent schedule and cannot commit to a raid group as a result, and doesn't fix anything.
