With one of the recommended talent specs, Divine spec Musicians are pretty durable and don't trade off much damage to achieve it. I cannot say how the other spec plays however, but I have heard its damage is quite low.
Also, there's really not much of a team over here anymore. All content, adjustments and development is and always has been carried out by KR. NCWest largely existed to manage the games in NA/EU but does no actual dev work in any way. They don't decide on balance, they don't decide when we get things, they don't decide when we lose things. It is all NCSoft in KR in all capacities. There is no 'working together' because there's significant evidence a majority of NCWest employees got terminated.
