IMHO, the game can be said to be fully ready in approx 2-3 years after release. When the worlds getting bigger, tons worth of content to play.

Right now dev.team less focusing on end-game content, many people after clearing coil they don't know what to do in-game until coil reset and this will continue for another 5 months or maybe after 2.4 when the next coil release, people will still always be like this.
Some people like challenging content, like pvp but sadly current battle system for pvp is dull like cat chasing rat games. You can see this video for example.

like XI's online the game wasn't meant to be ready since the first launch until their 3rd expansion the game was began getting really good and enjoyable. Playing other game or wait until this game ready. Your choice
