After three days playing it with my archer, I can say that most of the mechanic of this game are very refreshing, but so far I found some problems:
-Leveling until level 70 is easy because the quests and maps are linear. After that, I lost many hours just trying to find quests. The solution could add a warning saying that you need x level to get the quest.
-Is not a big deal, but why we can jump when we are on sleeping status?
-Some bosses knockback attacks are bugged and make people stuck on the air or outside the area. The area need to be checked also, because sometimes you can use the area to stuck them and make them lose your sight.
-NPCs and changing maps taking a lot of time, needing to relog and sometimes close my game. Of course, I know that is because of the beta.
-Gems dropping when you die is not a real punishment, it is just taking time to go to the store to stock them.
-Time Bomb Arrow seems like a very bad skill. It needs woe and more damage to be worth some points.
For the staff, very nice game! Love it!
