I always find it a bit sad when addons like massive raid warnings become normalized so I hope that doesn't happen...
Like the screen going red and a big audio warning telling you that a mechanic is coming and all that, it makes content feel so automated.
Same with addons that essentially make you have to '' play less '' and give you big advantages.

I don't have a problem with ACT and all that but addons that affect gameplay and makes it easier is a big nono imo.
As soon as that becomes normalized it essentially becomes the status quo and you're punished for not using them.
