I tried it in CB. The staff was nearly non-existent. I was forced to ask important questions on their facebook, and it took them much longer than I would expect to give me a response, especially for a closed beta. There 'response' was pretty much generic garbage, and didn't answer any of my questions.
The game itself is just plain bad. All of the classes[weapons] are EXTREMELY similar. Even the sword and fan[melee/magic] are extremely similar. There are literally only a few skills that are unique to each weapon, and the rest are just minor changes in damage/range depending on what weapon you choose.
When I played, there was no moving camera. I think they finally added it in, but I am not sure.
The game is horrible. It's very boring. It has an ingame bot if I remember correctly, although I am not saying that is a good or bad thing; although it is needed... later on, quests ask you to kill 150+ mobs per single quest. Most of the game's features don't really start until level 90. Luckily, you level up extremely quickly in this game. I got to 90 in a few days or so.
The main way you level up is through a specific event which gives you an hour to kill monsters that have a lot more HP than average, but at the same time, give literally 50x EXP - yes, 5000% normal EXP.
The game has crappy tutorials and very little information about it's features and systems. Because of this, you basically have to try out a certain feature to see how it works and what it does.
One of the major problems with this game is that once you hit 90, there are now literally 8 or 10 different ways to enchant/upgrade/enhance/improve your gear. You can access them all at once once you are level 90. Most of the ways don't work well unless you buy a lot of cash shop items.
This game is COMPLETELY gear based; at the same time, you need a LOT better gear than someone else to constantly beat them in PvP. For example, even though I had around 10-20% higher stats in all area's than my friend, and was a few levels higher than him, we still tied in PvP. What this means is that we both killed each other at the same exact time, and we both ended up dropping dead. I kept trying to kill him, but despite my slightly better stats[mainly from gear] and my alternating strategies, it was always a tie.
This game does have 4 or 5 factions if I remember correctly, which are essentially at 'war'.
You gain levels fast, so that's a good thing but not only is the staff non existent, but the community is, in the 2 days that I played I didn't see a single person playing, and I got to a decently high level.
Other than the lack of community and the lot of bugs, the game is pretty decent, it could use a lot of tweaking though.
