Console Players don't need Addons

[Punslinger]

They provide more than QoL elements to the gameplay. They can and do give distinctive advantages over console players.

Please enlighten me on how GShade, BDTH, or BMP give "distinctive advantages" over console players. Go on, I'll wait.

A poster here already admitted to me that healers can see the mitigation and ogcd heal cooldowns of their teammates. That is one hell of an advantage if you ask me.

No more so than calling out your cooldowns in chat, or raiding in the same room as your co-healer so you can glance over at their screen and see what's on cooldown, or employing a "ninth" to watch cooldowns and do call-outs, or...

I am trying to understand it myself. My previous question of why would a player seeking more difficult content support and use addon tools not supported by the dev team that makes the content less so got no response.

Why would a player seeking more difficult content do things like look at guides, or use meta comps, or use Discord instead of text chat, or run with gear above minimum item level, or join a static, when it would be far more difficult to do blind min-ilvl PuG runs with randoms? If you don't intentionally gimp your performance, can you really honestly say you're pursuing difficult content? /s

There are legitimate arguments against add-ons that expose information you could not legitimately get (untelegraphed AoEs), or that automate the game beyond what would be reasonable to compensate for a disability (automatic marker placement during combat). This ain't one of them. In fact, it's just a thinly-veiled Appeal To Motive against people you disagree with.

Seems to me players care more about the credibility than the difficulty. Thoughts?

I take it back, it's not veiled at all.
I think you need to drop the passive-aggressive act and get more fiber in your diet.
