Bomb runs - especially before adv tech comes along as they tend to go on longer.... I know it's better to appear 3k from the enemy base and blow it, but there's something more satisfying about going 6k or 7k, having your nans whittled down but just-about making it to blow up the base.
Initialising (or being a part of) game-winning moves (or game-saving moves) - for example I remember getting a bomb run going in a 30v30 game - everyone was like "oh nooo they're pushing a con" and I said like "forget that, let's bomb their adv sup, it's the perfect time" - got 6 people on my cause, base died whilst 45 people were in their con-push sector, game won
