Vanguard Mine Counter
Since you can only keep 4 mines down at a time in any game when you are a Vanguard, it'd be nice to know when one blows up so you can lay down another. Maybe there is a way to know this and I'm not aware of it.
There are times when playing online and there are only 3 people in total on the map and the only way to guard your outer CPs if you're the only one on one team is by mines. But you can't do that if you've already used your 4. Mines are a pain I know, but getting stuck on one map for 30 minutes or longer going round and round recapturing CPs gets boring quickly.
