While we're on the crit conversation and minions, I have a question. How are people running multiple crits against minions? For example, if you can crit on 1 advantage and roll 2 advantages against a minion group. Do you kill off two minions or do you kill off one and tell the player to spend the second advantage on something else because a +10 to the roll doesn't matter when you don't get a roll.
Good question. Per RAW you can only crit once per attack, so if you're going by RAW only one minion killed can be allowed. That doesn't mean you can't allow two to be killed if it makes sense, but doing so may lead to scenes that are quite overpowering, especially with a Marauder at +30 with Lethal Blows, killing 4 minions in one swing of a Vibro-Axe.
Although, Moses, that's not entirely out of line. The new signature ability allows a high-level Hired Gun to wipe all minions at once, so this isn't too far off, if used in moderation.
