My only complaints about camera options are;
• Console command must be typed every session while using the vanilla client (is there a .ini file somewhere to edit this?)
• Non bindable middle mouse button - my mouse doesn't suck but it's middle button press engages scroll functions making it extremely frustrating to use ingame.
• Oversensitive rotation.
Cardinal orientation isn't so much of an issue once you rebind 'reset camera' to an easily accessable key (you'll be using it often). Also I like being required to watch biome shapes and landmarks to tell where I'm at.
I quite like isometric camera angles for their framing of scenes.
