Flack/Missile/mortar launch method

[Crackling]

I am well aware of how weapon groups work, and use them all the time. The intent behind the suggestion is to eliminate the need of weapon group for Flack, Missile, Mortars. and make the combat more fluid, slightly of course but still.
Why should't i consider something that could improve it, and making it more effective.
Think outside of the box.

So, why would you need other six groups?

Changing something in game may cause new bugs, so developers might be against doing that...
