Grenades are very, very underused in this game. Which is a big difference from BF1942 where many players used them, sometimes overmuch. I think its mostly because you cant reliably take down armor with grenades anymore and the lack of ammo boxes. Since I mostly play support, I dont have to worry about running out.

Grenades are the easiest way to clear a flag and prevent it from being capped. Most people lay down on the flag, so even if they see the grenade land, they dont even have time to pray. If they run, it clears the flag and makes them easier to shoot. If they survive the explosion, they are wounded and possibly shell-shocked. Not only is it possible to take down multiple targets, but you are more likely to kill the medic too. Either the medic was killed with the first explosion or he will run into the next explosion if going to revive. This is more effective than going in guns blazing trying to clear the flag.

Meh. Sometimes chucking grenades is only a big "look, we're coming from this direction" for the enemy if they make it to cover in time. It might seem like a barrage of 4-6 grenades will kill everyone, but if you see them coming it's quite possible to avoid them, and even throw some grenades back. Unless I know where the enemy is and can deliver grenades right to them, I'd rather the element of suprise.

Doesnt make a difference from what direction they know you are coming from if they are dead. Anyway, with UAV, spots, and scans, I always assume they know which direction I am coming from. Better to go in knowing that you are being hunted rather than thinking you are some type of ninja.

Yes, grenades can be avoided if you see them coming (emphasis on if). However, it is more common not to see where they came from, only the resulting explosion, which doesnt help the target anyway. I've dropped many a grenade down from the rooftops. Many people would spin around after the explosion but no one has ever looked up. Even dropping multiple grenades at the same time onto the same squad only resulted in confusion and death (for them). Anyway, if they are concentrating on avoiding the grenade, they arent concentrating on shooting me. Since grenades are underused, I rarely worry about being killed by one in return.

The purpose of a grenade is to clear an area. To say "I wont throw a grenade unless I know where the enemy is" is ineffective thinking. Saying that means you walk into the ambush first. If I have any doubt about whether a position is clear of the enemy, I toss a grenade. If the crosshairs dont blink, then it is clear. If the crosshairs blink, someone is waiting for you. I dont climb up ladders to check if a roof is clear or peak around corners. The grenade lets me know just fine.

And yeah, I hate it when people run into my grenades too.
