I don't want to speak out of turn for this one, but my *belief* from testing the game, is that the comet trail is there on batting, bowling and fielding.
I think Ross has just gotten so used to the system that he doesn't notice the trail (which in it's unobtrusive nature is easy to do).
Personally speaking, I think it's one of the best elements of the game and makes batting really dynamic as you don't know where the ball is coming until it leaves the bowlers hands and have that good little split second element of reaction to pick up the trail and mould your shot to where it's going. It adds to that feel of real cricket and gives you more immersion to the mechanics, especially compared to what we've seen in the past with cricket games.
The trail isn't in anyway 'overpowered' or some such thing, where you are able to easily exploit the bowling due to it, it's just a helper element so you can pick up the ball every time.
Obviously it'll be up to the team to decide whether or not to allow the removing of the trail, but speaking from personal experience, I don't think I'd be removing it anytime soon.
