I like practicing using Jett knives to kill bots, but they don't trigger the buttons (as can be seen below), so I always need to switch to my gun to press them. Other "weapon-like" skills (like Chamber's gun or OP) do trigger the buttons....

I'm assuming its to make a more balanced experience, but is there a reason why there are like only 4 abilities that almost every character has just in different colours. The characters listed are just off the top of my head. 1) Flashbang....
