Player skill level classifications

[Penthea]

What are your thoughts on this classification list?

That it's incorrect. Players can't always be put into nice neat little boxes with labels. Often players can have aspects of themselves that are both casual or hardcore and the places inbetween. Each shade of grey has varying shades of grey.

Never mind how pve isn't the only progression route in the game that can require time, skill, dedication and hard work. Crafting is a whole progression route on its own. I doubt anyone who knows what it takes to be a consistently top tier omni crafter would call them casual even if they don't raid. Roleplaying can actually be super tough work if you're organising rp events. Pvp is another type of combat with its own challenges that has different demands to pve. You can be hardcore or casual in several facets of the game.

LOW CASUAL: Pure fun player.

You were incorrect very early in your post. How is being a pure fun player unique to this grade of casual? Contrary to what you might think "pure fun" is actually the goal of most players regardless of the effort and time they put into the game. It just so happens different players have different ideas as to what fun is.

Low is not meant to be a negative descriptor.

Maybe not your intention but looking at the list as a whole you have clearly created a hierarchy so low ends up looking...low.

why is such a thing necessary? Just play the game how you want to play the game, no need to shove everyone into a rigid class structure.

It's not necessary. It doesn't actually lend any useful knowledge. Reading OP's list doesn't make you better equipped to deal with anything.
