I have come across a couple of articles which require using ADB to change the default install path, but I don't want to go that route because they are mostly for stock Android devices so I am not sure if the method will actually work on the HTC One or make things worse?

Unfortunately I received the 16GB version so it is not enough for me. I have an old 4GB Scan Disk which I am using right now but the phone tells me it's slow and I should go for class 10, so I'll be doing that in the next couple of days.
There are large apps and games on PlayStore which I'd like to download directly to the External SD Card, which is why I'm asking about this.
