You probably need to spend a minimum of 150-200 dollars if on BDO if you wanna take it seriously. I played it seriously since February and just quit last week, the game really sucks you dry of time more than anything if you want to be efficient.
That said it's basically a game with great graphics and combat, and a really shitty system for gearing up. Just for reference, there's not a single player in BDO that is "Max gear" as it takes inordinate amounts of time to even get a single piece of gear to its maximum enhancement. That said the flip side of that is there is always goals for you to set to progress further.
The game is a marathon, not a gear sprint.
