Well , thats great, I'm alway open to how other people play BUT, that in no way tells me what the actual rules say.
I've played many different systems, often with rules that have been played a certain way only to find out later that we have been misplaying a rule.
House rules do not help in deciding what the rules are, in fact it only confuses the issue.
No one has stated the rules, or the reasons why they play it this way.
For example Anti drone states " Roll a die for every Attack Die of drones attacking a ship...."
Where Stealth states "For every hit a ship with this trait takes...."
These are two different things.
As it stands the ADD has to roll as many die as the drones have fired, no one has came up with a good rules argument otherwise.
Good fluff reasons yes, but fluff does not =rules
