I think it doesn't matter what a missile actually can do.
The LRMs are described as rather dumb and unflexible as far as I remember.
Think of the high tec you need to build a BattleMech and now think again about human aiming.
Now and in future a targeting system which locks onto an enemy should automatically guide any weapon directly into the target.
Especially a target which is as slow ans big like a 'Mech. But that would be no fun and no challenge.

For better gameplay I would prefer the method of that target widget on any friendly 'Mech to fire LRMs.
Otherwise a public team without TS/Ventrilo has no chance against another team with just 2 or 3 players of a clan.
Ok it would be good for hardcore players organised in clans or even lances and it would be more complex but it can be much to powerful at public matches.

A lock-on info in my cockpit with a hotkey to confirm would be easy to handle. Great idea!
Hmm just imagine than the widget comes up and you fire your rockets. Just like in a Hawx video I saw a few days ago.
(http://www.gamepro.de/videoplayer/popup/video.cfm?pk=243&id=video it shows you where to fly to get in best postion to shoot)
I'm gonna loving it.

But I hate chats. Most of the time I'm busy with fighting and don't look if someone wants to chat.
And I think a raven pilot trying to keep his aim onto the target while stay unseen or in fast movement also doesn't have the time to type a lot.
Only option would be a "chatsystem" like BF2/2142 has. It's fast and easy to use. But when I think of the amount of messages coming from that ...
It's just talking and talking ... does anyone really react on this talking? I only use the new info on my radar.

My argument is for usability over complexity.  Remember, this is a mod of crysis, not MW4.  Selecting a target is brand new code for them, so adding anything else onto it makes it more complex.  Having the ability for one player to send a message to another is not as complex, even if that messages takes the form of a HUD widget with some targeting information (like the type of mech being targeted or enemy name.)

And maybe the rockets do have a hard time turning in at 30 meters to a NARC signal, if they are moving at super sonic speeds then it will probably be easier to hit with them in the first place so it might add a few extra missile hits, which is exactly what NARC is designed to do, increase the number of missile hits by about 20%.

Not a bad idea

Like the C3 thread and anything in "Ideas and Suggestions" it is just brainstorming and brainstorming only.
