It’s a shame that many expeditions fail on normal mode just because many players do not know the mechanics. I personally do my due diligence and spend a lot of time watching YT tutorials, read forum posts, reddit, guide sites and what have you. Though I am aware that I am a minority in this sense.
What is the issue really? Well from my experience it is quite simple, normal difficulty expeditions are often filled with those who know and those who don’t, it is just so many times you bother having to explain mechanics to players who are new to a expedition before you decide f*** it and yolo it. I myself often fall into the latter, because again and again you try explain something and its either being perceived as I am trying to s**t on someone or that I am being an elitist, so I just shut my mouth.
I have seen many attempts to remedy this in games over the years, some good some bad. Maybe the more successful was Deadly Boss Mods in World of Warcraft, this addon would clearly notify players about upcoming or ongoing mechanics, are you standing in a AOE effect it would tell you GTFO, standing in front of a boss when its about to do a one clap ability etc etc…
Some games also have short descriptions either by text or short video snippets before encounters to explain different mechanics, this is also quite effective because then everyone is on the same page. I see way too often people trying to pull off weird stunts just to skip a simple step that in the end fails horribly because this one player decide to go rouge mid fight.
A perfect example would be Isabella fight in Dynasty, on multiple occasions I have seen healers pull one of the dogs into the corner behind the cage to get it stuck, I see that this tactic fails just as often as it succeeds. And especially if the group is not aware what this one person is about to do, and this is border-lining exploitation.
Running expeditions is so much fun when it goes smoothly I really hope that more people get to enjoy it, but sadly because there are almost as many tactics as there are people it is really hard to get excited to do these through group finder.
As many more have stated the irony is that once you get to mutation 3-5 expeditions become much easier as normal and first few mutations have acted as a great filter.
