no way you can be a great player if you use mouse4 to push to talk rofl mao are you kidding me
what happens if you stand at the back of B platform on dust2, and must call and shoot at the same time?
You can't wait to give that info, not even for an extra second.
You must call the split second you see them rushing B, and you also have to fight them in the tunnel exit to make sure they don't spread out and take over B and win the round before the bomb is even planted
And my point is you can't be a good player while using your hand to both shoot and communicate.
Yes, you might be a decent player but you won't be great. Hand/Eye coordination skill will be affected by having to use your thumb to press mouse4
