I think using an audio communication method would be bad simply because to communicate we would have to chew up some mad bandwidth! UOAM would be easier (probably a little slower to type it out, but wouldn't cause severe lag in say champion spawns. )
As to having used it, my friends and I used to use
--messaging all the time. It worked pretty well, all 5 of us could see where each other were and send messages. Also if someone died or needed help in some other way, desperately, we didn't have to keep asking "Ok, what area are you in? Where? Where at now??"
On another note, though, you must have UOA for the --msgs to work. Though, even with an UNREGISTERED UOA these functions STILL WORK as it just something added in to compliment UOAM.
Some useful functions:
-find playername (focuses map around that player..or yourself if you use your name.)
-panic (use once to go into panic mode, all other players have lines drawn from them to you on the map and the map blinks. Use again to end panic, I believe)
--Text (send message to all AM users)
I'm sure there are some others I can't remember. Anyway, back to my hobbies. :sleep:
