The general player base needs to improve

[ThirdChild_ZKI]

The reality of the matter is people will play how they want to, given nothing forces them to do otherwise. Its not like the devs are going to enforce minimum skill level requirements in casual content.

They already do enforce a minimum skill level. They do so in the form of enrage timers, instance timers, and HP values. If players are unable to successfully deplete enemy HP values before their own are depleted, or before enrages or literal time outs, they are simply not meeting the bare minimum skill required, and if they can't do that, at level 70 now, that is VERY bad.

Let me paint it differently:

You can tank without ever using defensive CDs because that's how you want to do it, but that will never mean you're doing it right.
You can be an Ice Mage all you want and never run out of MP, because that's how you want to do it, but that will not be enough for anything beyond the most casual content.
You can do "just enough" to get through content because that's how you want to do it, but if and when the bar gets raised, it won't be enough anymore.

And it goes without saying that there's something fundamentally wrong with stubbornly adhering to wanting to do things your way, if and when placed in a situation that requires teamwork. If your way somehow increases or complicates the burden on others, then that's simply selfish and a direct and negative impact on teamwork. There's no I in "team" but there IS one in "fail".

I'm so stealing this quote.

Firstly, I fully understand what people are arguing and how being inconvenienced by poor play is frustrating. The only point I'm making is that its not going to change. Since ARR launched I can't think of a single dungeon or NM primal that I've been unable to complete due to player ineptitude. 24man riads can be frustrating at times, yes..... but they aren't as bad as people on the forums like to make out either. Savage and EX primal are another topic completely given players tend to make their own parties for the content.
