Please, can people stop throwing themselves at each other's throats?
Let me just try to make some points a bit clearer outside of the garbled mess of people going at it with emotions.
To define what we could potentially call cheating or for a less grievous term, artificially lowering content difficulty. One of the simplest ways to define it would be anything that does something for you instead of doing it yourself. There's no ambiguity nor doubt about it I believe?
Parsers, ACT, whatever DPS meter you like to use. A tool that serves to analyse someone's efficiency. In my humble opinion, I believe you don't actually need any of that to just clear. As far as I've observed so far, content works in a way that, as long as you regularly make use of your CDs, keep your GCD rolling as much as you're able to and prevent mechanics from killing or lowering your damage, then you can clear. The whole parser, ACT and so on only serves so you can do it faster, which is arguably trivial.
Consoles can't have addons, they don't need them either. PC don't need them either but they can't be stopped from using them.
As far as I see it, some people are trading the fun in playing the game for over-efficiently clear content. Not saying there isn't any fun at all in being good but when you get a random thing telling you how to play...I don't know, to me it feels cheap, weak, bland, empty.
I think these few paragraphs do make for a better objective of discussion about the need of addons, whether console or PC and why. Can we please talk about these points I made? About the whole trivialising content or not?
PS: Shaders and other non-gameplay affecting addons are mostly the personal preference of whoever so I don't really have a way to fairly bring points about it.
