Even more so when 9.15 hits and you can have x25 zoom. You can actually unbind the shift-key from the settings as well. Nothing is more distracting than having a close brawl and having forgot to change the zoom from x25. That shit is so confusing to my brain.....
That being said, I've played combined (10k NA, 5k EU) 15k battles with shift, we'll see if I ever change my ways.
My "pro" tip:
Don't use XVM, treat every opponent like they are equally dangerous. Sometimes tomatoes pull stuff you didnt expect them to, resulting in you losing HP or the whole tank. Especially win chance on the XVM is cancer, pubbies throw games just cos mod tells them there's no hope.
