Camera work is one of the most critical and easily over look parts of casting in any game. When the camera work is done right, to the user they will never notice it. The perception is that you're just doing it right. Do it wrong though? Miss a key kill? And the viewership will quickly get upset.
Personally I've found camera work to be highly enjoyable and somewhat stressful. You're playing a game which can virtually never be won. Trying to find the balance being using your game sense, cheat feed and listening to your casters. If you enjoy a good challenge, this is definitely up your alley. Lets get started.
