I've played the CB when it released, and yesterday I was expecting the same shitty bugged game it was on CB. To my surprise, the game has improved a lot, A LOT.

They added dodge for all classes (a new stamina bar to dodge/run faster), improved several game features and even graphics.
The game is not awesome and has many flaws, but it's better than the majority of F2P crap that tends to release these days. The Cash Shop is not very expensive either, which is nice. You can also gain CS currency through the AH or buy anything from CS with tokens from daily quests (similar to RoM, but you can buy anything...tho it takes a while to buy the more expensive stuff). It has some P2W crap from a first look point of view...but the time will tell.

In about two months, they changed the game completely, and it's not because is a localization of an old asian game since it's releasing nearly at the same time as the TW server. (about 3 weeks of delay or so).

And btw, for once the NA version was shittier than EU version. The build version was the same, but I saw NA had a lot of server issues, lag and so on...EU server works (during CB as well) just fine and yesterday they did a flawless pre-release...let's see if today they can keep it or if the servers will explode as always.
