Have you seen the RNG chances for Kor players to get things?
They are about 10x higher than drops on Western servers where they don't have to publish %chance. Regardless, westerners moved away from a grind-based-ethic where they were sold on the myth that hard-work leads to success. Most know that hard work == wage-slave working-class. You think they want that in their entertainment or games?
I've seen many times when someone calls you on your made up "facts". Your credibility is too low to use phrases like "believe me". That said, though, there are multiple issues that aren't being handled well that are contributing to players moving on.
So so wrong. As a player, very often, the *only way* to progress is by finding other ways to raise stats than by upgrading weaps+accessories. If you can't get into a RAID because your clan only does 1 raid which is filled with players with higher stats, DPS and AP than you, you have no choice but to look for other ways to raise those things. Things like gems used to be considered either whale or endgame items -- yet it was the only route open to me to raise my stats, since I was constantly kicked from F8 groups as a lower player and not invited to the only raid in a clan. I've only been in 1 clan that ran more than one raid, and that clan fell apart because they couldn't keep filling those raids in the face of too many players leaving the game for various reasons. Things like psyche's are ways of raising your stats in spite of not having access to 'IA', (now, for example). It's not a replacement, but it does help. I have no access to an IA raid I need and can't solo dungeons to get ET-level accessories or upgrade mats. I have to rely on groups where I need to qualify to get in.
The dungeon related costumes STOP at BC and above. They should put those costumes in easy mode drops as they are previous-tier dungeons. Maybe keep costumes in elder-scale dungeons in HM, until there is a new level above IA, but there's no reason to not make costumes in onyx-mat dungeons available in easy mode like previous dungeons.
That's bull. Where are opportunities to get items or achievements like Eagle-Eye, Sapphire-Flyer, let along those from events like Fashion Police, Fire Runner, Bloody Valentine, Defender of the Ancients, Heart Stopper, etc... If they would repeat the events, it would be possible, but they haven't, so your "simple" case doesn't exist.
