Of course it is, I only play PVM content remember? duh.
New content will always come up to make the game better. Again this game is their CASH COW. They will always improve this game.
When players do not get their game experience improved, it gets boring and people leave duh.
You only play PVM content, but you can't defeat current MVPs with current gears and need to be spoonfed Kafra shop items. That's actually really really sad.
If you look up on the statistic for Gravity, the game's population, retention rate and revenue is dropping, nothing they have done as of recent is improving the game. So your argument is invalid. The direction of the game they are driving it towards isn't working. And that is actually pretty alarming.
