it tells me where people are, if we are holding a position, pushing up a position, where we need more people, if we are being flanked, if one of my teams sniper dies where i can pick up his sniper gun.
I agree with Bill, I use it all the time, especially when advancing and I can't necessarily see the person in front of me, I check the minimap to make sure that if he dies, I'm ready for whatever killed him.
Used in conjunction with the messages about who kill whom, it can quickly tell you the location of much of the other team, and with a bit more observation, their playing habbits. I use it all the time.
I use it too, especially on Kalt. If Tangerine is camping on top of their second ladder and killing all of my teammates in sewer I just chuck a nade upthere
He's still positive against me though
Honestly I don't see the need for it as long as FF isn't on. I mean if you doubt what team your target is on, shoot anyway. Enemies die, teammates don't. SPAM THOSE NADES!!
Yea i mostly end up using the mini more often on FF enabled servers. But its good for meeting up with a teammate going for a flag cap from a different route.
The mini-map is the single best tool in the game, I suggest you all use it... it only makes you more aware of your surrounding and a better tactical player.
