Here's a question tied to the "rolling too many or too few dice" issue.
Say you're playing against someone who has ships that roll a lot of dice (HLC Agressors, for example). They have a tendency to roll their dice one at a time, until they have a full roll. I have personal opinions about rolling like that... but this isn't the place to discuss my feelings.
There are rules that address rolling too few dice (roll extras to make the difference) ....but what happens if they then go on to (oops!) roll too MANY dice? Say they attack with HLC, and roll one at a time... blank... focus... blank... then they accidentally drop two dice that come up hit-blank. The rules state that a too-many-dice attack is rerolled in whole.. and the whole thing begins again, this time probably with a better roll (the same situation could arise with defense dice on a fully-kitted-out Soontir Fel).
Do you have the right to ask your opponent to roll their dice all at once? Is this something that could/should be brought to the TO's attention? While extremely suspect, it can be completely innocent - where do you draw the line?
The rules say that if you roll too many dice, then the entire roll is ignored and you do do it again correctly.
HOWEVER - the intent behind this, as I see it, is that you can't tell which is the "wrong" dice, so you can't just pick it out. In this particular instance of someone rolling their dice one at a time, and you can see which is the excess die, I would be happy to simply remove that last die from the pool. It'd certainly be quicker than watching as he picked up all the dice and rolled them sequentially again.
