The best part is if they bank it messes up the sitting positions relative to others. I was told I was taking things to serious when at the Store Championship I played at yesterday when my opponent moved both daggers and went back to focus the first one and I said he couldn't. My understanding is you move and then action. So did the guy also move all and then claimed to give all an action. I would only allow him to take the action on the very last one he picked up ( outside of Using the template for movements).
If they're the same PS, yes, you're being too uptight. If he wants to drop tokens at the same time, that's fine. Now, if he's going to barrel roll after moving both, that's a big no no.
Yeah I don't think there is any problem with moving ships with the same pilots skill together (with templates!) and then taking their actions at the same time.
Yeah, you'd be an ass if you didn't let him take his actions (Focus, evade, TL, NOT roll/boost). Is that really how you want to win? On a technicality like that? Be a good sport and let it go, it's just easier to do it that way. In fact, I'd remind a player if he forgot to take an action.
