The Nuisance of Tornado Spin

It would be better if you just hit the key to activate it and then hit it again to do tornado spin, in my opinion. I don't like having the regular attack key in my normal keys, anyways. It also bugs me as an aran when I am at Zakum and I keep rushing into Zakum since I am getting knocked back and instinctivly press the arrow to walk towards Zakum all while I am still spamming the attack key like I have been my whole career.
