I will not blame you lack of knowledge on stupid player and new player but I will try to explain it plainly what you say about people having "A EASY TIME" gearing to mythical is also a myth.
•So let's begin by this: CSNM is clearable by the most stupid people, and it's possible to do it without even looking at the fcking screen.
Well I dunno which CSNM to be able to play it without looking at the screen during the "fear / rage" mechanic but I would love to play the same game 
Then "the most stupid people": are you reffering to new players ? Like those who recently came and don't know much about the game ? Then I assure you they can't :D. Yesterday I was in a matchmaking party for velik sanctuary with my new alt (a tank cause GOD I HATE W8TING 30MIN to go into AQ/GVHM etc via matchmaking). Well I was with a new player (a healer) and 4 people who were kind of begginner (lack of skills). 40 min for this dungeon and at the end I explained to the healer where he could find advices on how to play his class and before each boss I explained the mech. Nevertheless there were a lot of death.
SO if by stupid people you are reffering to new player, even if they were mythical +15 they could not do it cause they lack the skill to do it.
Now the second category of the so called "stupid people" I name the people who have skills but 0 cheat (cause yeah with cheats every dg is easy well maybe not every dg because sometimes the cheats can't keep up with the pace the boss is attacking). I daresay that this category of stupid people was lagging behind at the time people were training for CSNM then they did not experiment the mech, and only looking at tutorial will not help experience is also necessary. Well those stupid people are NOT accepted in party (y) except if they have friends or connexion which make them only have the solution to use the matchmaking option (remember my point about making an alt lancer?). This means that those stupid people will have to wait for a benevolant party to accept them or create their own parties.
Thus your point about "the most stupid people can do it" is invalid. People with a bit of skill and a regulat party have done it and do it easy peasy is more accurate. But even so it take times to learn mech, or have someone who is able to call for the other.

•Now the part about " best in slot gear has ONLY been available from the hardest content available."
Again I disagree (but at the same time will propose something else).
I desagree because making it this way is plainly stupid as
1) some people mentionned it but CASHHH SHOOOPPP (do you want this game to be classified as P2W or P2F?), don't you find it stupid that people who grind CSNM for their gear will fell excluded when people who do CSHM exclude them cause they are not geared up?
2)as mentionned before the "stupid" people will not get to down CSNM anytime soon (I helped a guild as a healer for AQ yesterday night too and they were far from killing the boss easyly).
3) For me the hardest dg should not reward gear but prestige
Then what do I mean by prestige ? It can be a shiny title, a skin, a mount. Anyway something useless but which show to the world that the player has some skill (remember bahaar statue?) . Thus instead of focusing on "gearfor the hardest dg" they should introduce something similar to the reward they will give for the pvp event. THIS would be rewarding and make the latest dg "worth it" even more with the limited number of entry one have.
I do not force you to agree with me on it. But if gearing is you high end content dream I find it a bit sad.

by the way I also agree with some people that downgrade should be banished, I did not like it when it was the case for VM / pvp gear so I will not like it anytime soon xD
And it's true that they should reintroduce content, even the flying castle could be a good idea to have an "healthy competition" both in pve and in pvp (cause civil unrest is meeeehhhhhhh).
they should also reup the content of fame rewards in the different factions (new exclusive skin a flying mount etc) but this talk is for another time ~~
Finaly, thank you for your rage but if next time you post something you could be a lil bit more aware of the fact that insulting new players is not a good idea it would be quite good. It does not give a good image of the community (even if you probably don't mind) but so you know now
