Let's ignore the knowledgable people helping out casuals assert, because expecting people who heard all that to create their gameplay more efficent waste time on cheap wow classic gold helping others goes against the idea. And of course that again, the aid offered will only make their experience worse.
They'll help them even though indirectly. The sheer amount of material you can simply buy with gold is another thing for casuals as well. Hardcore tryhard nerds who rush the material to the end and do constant high end raids will spend huge wealth on raid consumables with very little downtime to get them or create these matts themselves. This means with minimal effort or time invested casuals can make quick cash off the elysium project nighthaven gold AH then turn around and buy premade pvp groups complete armor sets and also get to raid content since the remaining folks in that category need their cash.
You can inquire asmongold himself about this he's said multiple times even though his mother has been far more casual with a player she often had better equipment simply due to the fact she perfered to spend her time golden farming and exploring which result in her being able to only buy out the armor she needed.
Hell I knew a few people in my guild back in the day who would gold farm and end up with higher tier armor than the rest of the stunt grade group up before AQ40 and after that they simply bought pvp material out. A premade will allow you to sit base while they stomp a pug for honour out they would alrdy be getting together with the added bonus of a couple hundred gold each runs.
