3.)Repeat steps 1 and 2 for however many launchers you want, just log in to a different account each time.
4.)Click "Play" on the launcher
5.)Search through the handles in "DragonNest.exe" for "\BaseNamedObjects\MutexDragonNest" and close it.
6.)Repeat steps 4 and 5 for each launcher.
I haven't experienced any d/c issues with this.
