I had to pop in offline and check to see why I don't use mouse views. It's too slow to track, and you have to hit a key to get back to a forward view or you'll be dragging back. I'm sure I could mess around with the options to get it to roughly what War Thunder has, but feh. It's easier for me to F3/F8(?)(I can't remember if it's F8 or F9 that does a "slow" scan vs the snap scan) and scan for targets while in a bomber/GV. And the default method of scanning with num key's works in a fighter for me.
If you are going to keep it, it will need to be changed. Hitting and holding a key, using the mouse to scan, then letting go of the key for your view to snap back forward; set as a default method would work. It's default scan speed would need to be boosted a lot, to help with searching for/tracking cons until engaged.
If you are going to get rid of it, it won't bother me as I currently do not use it.
