Watching the world first race I am honestly just confused most of the time, it's so hard to see what's actually happening.
Things look like they're going fine but then suddenly the tank and whole group just dies to seemingly nothing, the game rly does a terrible job at telling you what's going on.

At least in FFXIV I think even if you don't play the game you can still with some common sense see some tells and at least know that something is going to happen even if you don't know what.
In WoW it so often just looks like the boss is auto-attacking and then BANG, everyone is dead.
I actually remember this now thinking back to it too when I used to raid especially with my guild in Cata, I always felt like things were going fine but then we just died and I'd have no clue what happened.
And we weren't horrible or anything we did clear the content but I still remember being left with the feeling that deaths were a mystery too often.
In FFXIV I can see exactly what happens and why we wipe, it's very rare that the group wipes and that I don't know why it happened.
