Still don't understand why people oppose this, its just a suggestion to add an OPTION for aiming with a keyboard. Mortars and howitzers would benefit greatly from this, and obviously the normal field cannon wont. Why not?
Also don't retort with "It will make them too powerful"
Well, that is the case only when you have a very good artillery crew, which is fairly rare in this game unless you're in an organized match.
A good artillery crew is 2-3 players all in teamspeak: one is a spotter relaying distance to the cannoneer, one's a cannoneer, and one is the reloader, just a head up for people who dont know.
