I've had some really bad experiences doing Ex trials that were reminiscent of playing with people in Call of Duty on the Xbox 360 and world of warcraft. I've had people throw "soy boy" around in chat along with insults and political garbage or just being plane passive aggressive. Often this is paired with people marking a group as a clear group instead of a farm group when SE implemented the "Duty Completion" flag among other issues.
The problem right now is that SE wants to drip feed content and put a carrot on a stick to get people into that content. They aren't releasing Anemos because they want everyone who wants a weapon doing Tsukiyomi EX first, which sounds backwards and basically trying to force people back into the old raid guild mindset of 2009-2012. I don't want to feel like I need to start chugging 5 hour energy drinks after work to spend time grinding ex content just to make sure I don't miss the wave on them. The entire reason people like anemos is that it's easy to step into, can be done when you're not at your best, and lets you make progress incrementally. EX content is all or nothing and promotes some really toxic experiences.
I mean, they are hold back the new endless dungeon, too, and that probably has the same hard mode floors past the top like POTD did, which is basically mid-core content.
