I'm not talking about outright removing them from the game, but the CTRL+ALT radio commands seem like they need to be A) Trimmed down slightly, and B) Replaced perhaps with similar voice cues, but used things that actually coincide with the game. E.G calling for mines in a building, or calling out that a building is clear of infiltrators quickly.
Seriously, when was the last time you used 'Watch where you're pointing that' ? Seriously.
On top of this, a good number of these commands have been woven into Q-spot, which is far faster, albeit unable to be used unless you can see/target the structure.
EDIT: Some of the major candidates for getting replaced/removed
"Enemy Spotted" [Made obsolete by Q-spot which has more detail anyway]
'Destroy That Vehicle' [Once again: Q-spot]
'Watch Where You're Pointing that' - [... Just Z-Taunt to yell at people.]
'Don't Get In My Way' - [This one's actually iffy... but still probably you can just shoot at a teammate if they are in the way]
'Destroy it Now!' - [Same as Enemy spotted/Destroy that vehicle ]
Perhaps ALL of the CTRL+ALT commands if proper 'building cleared' and other messages are implemented.
