I was in a key the other day with a guy not running DBM and every time thundering went off, that guy would end up getting someone stunned because he wasn’t paying attention to it, and nobody else could find him. The giant chat box with an X or Square is mandatory imo for finding your thundering buddy. I don’t play with friendly nameplates on so I can focus on enemy nameplates. If I had both on I’d be accidentally clicking on them / they’d be cluttering the screen most of the time.
The UI displaying important information to the player is part of encounter design though. Personally I’m highly reliant on GTFO / DBM to make sure I’m not standing in things, because there is so much visual clutter in the game that it’s very easy to be standing in something and not realize it. Floor effects are almost always a very similar color to the ground you’re standing on. Even when they aren’t the edges of the floor effects are frequently a gradient transparency so it’s hard to tell where the edge of the ability really is and where your own hitbox begins. It’s super easy to get clipped by things because it wasn’t clear where you couldn’t stand.
So most of the time it’s manageable right, like… your basic “don’t stand in the fire” “interrupt the spells” and “stand in the soak symbol” is a good chunk of the mechanics. When I say overwhelm players with mechanics-- I mean quantity generally. Like Nokhud is a good example. You’re in a grassy area, mobs are doing big green semi transparent wooshy things on the floor near mobs you need to interrupt – It’s pretty important to get those interrupts you’re not able to get to… while also having to find your friend you need to clear thundering with… and then you have to find your white ghost body, while birds are doing the huge white semi transparent cone attacks, while also having to kill explosives all at the same time, and only having a couple seconds to do all of those mechanics at once.
Or in RLP where there pats everywhere on the upper ring, mobs that have to be interrupted, swirlies not to stand in, you have to find your buddy to clear thundering with and maybe they’ve got the fire bomb on them so you can’t go near them… etc etc.
It’s just an overwhelming number of things that all need to be done simultaneously – while also tracking all of your buffs/debuffs to try and maximize your own damage output. Like trying to do that while looking up at your buff bars and tab targeting through all the mobs to check your dots, checking whats coming off CD for/how many Cps you have… hoping the mob isn’t too tall for you to see their cast bar on their nameplate…
None of those things are hard on their own… it’s only difficult cause they’re trying to overwhelm you – and that’s less difficult and more in the frustrating category… and it’s compounded when you’re getting hit by things that are hard to see.
But they’re okay with making things hard to see, cause most people run addons that tell them when they’re standing in things they can’t see… and they don’t need to read all the tootlips on their buffs / constantly look at their action bars, cause they’ve got a nice weakaura that shows them what they need to know in a very visible spot.
It’s like… not one specific thing… its like death by a thousand cuts from all these little things that are piling up.
