One issue with the Trust system is if you die, the healer can't rez you and there's no players to help with advice and mechs. You could be there in the 90+ dungeon for hours and hours and hours resetting and still never get it.
I mean I played through all previous content, been playing about 9 months, (yeah the 2014 Vets can laugh, I was over in ESO since 2014), and couldn't quite get the mechs in a couple of the 90+ dungeons with the Trusts. Queued up with a pug DF group and still died a bit but had some nice players help out with tips and advice.Got through em no prob then and was able to understand the mechs much better with live guidance.
The one sorta relevant point which was made in another thread, regardless of refugee or noob status, if a player hasn't sincerely done the previous dungeons/trials and seen how mechanics build and operate, they're going to seriously struggle in current dungeons.
Still, I'm proof you can have done the content, be dedicated and genuinely trying, and still be hot dying garbage in new dungeons lol. *shrug* Idk about anyone else but it takes me at least 5 runs in a dungeon to really grasp most or all of the mechs. If there's some elite players amongst us that can magically get everything their first time or by just watching a video once, I do commend and congratulate their skill. <3
