The engine is crap, though. Besides the memory leak and overall frame drops while using some powers, vsync option doesn't seem to work, changing particle resize and buffer options requires a restart to actually change, exit the game and change them on the log in screen and it will work, (change them, then open settings again, they change back) and the game uses a software mouse (hides your actual cursor and draws one on the screen, which is affected by frame drops, resulting in unresponsive mouse movements in frame dropping fights).
I also cannot set fullscreen windowed mode without a crash to black screen unless I edit an .ini. Mouse smoothing is also enabled by default in an ini with no in game option to disable it.
