Dungeons aren't so bad, but yeah, every raid and trial you'll meet is just, go figure it out yourself.
But to be fair, that's how max level players learn too, when the last new raids hit, you jump in and watch what the boss does and learn from it.
It's fine if you die a couple times, as long as you try and pay attention to what killed you and learn from it!
Don't just stare at the boss cast bar, also look at what the boss is doing, many raid bosses have telltale signs of what's gonna happen if you just look at them.
And don't feel bad if you can't remember them all, if I get into an older raid or trial I often forget the mechanics too and have to relearn during the fight hehe.
But most bosses share tons of mechanics so make sure to learn what a stack marker is, to look away from the evil eye, etc etc .... if you know these, you probably know half the fight of any raid in the game.
