You know the quote "The best camera is the one you have with you?" Applies to flashes, too.
Yes ... but it makes you lazy too
You end up using the on-board flash rather than an external flash, which you can bounce or use with a diffuser.
So, I'm actually all for removing the on-board flash on the 7DII.
I'd rather have WiFi (and a bult-in radio transmitter) than an on-board flash.
