That is definitely naughty, front arc is clearly in arc on the enemy ship, but because of the rules, the side is blocking the shot?
They need to fix that, as the guy said, how can the side of the ship be blocking an attack? surely it would sustain the damage instead of the rear.
But what use would the LoS dots be if not for this exact situation? You're pretty much advocating for an arc-only system, which I think would take away quite a bit of the depth that makes maneuvering a challenge in this game.
Gods remember when people would just measure Dot to Dot never checking arc. . . I still have some people who have not played in some time doing that. . .
I've said it before and I'm still a 100% advocate for changing firing eligibility to just a LOS check. A shot is possible when dot-to-dot measurement only passes through the firing and target arc. In the pic above, the VSD could fire at the AF's side arc, not the AF's front. It's infinitely easier and quicker to execute, visualize, document, and teach. I've never met a player who has only read the rules, including the RRG and FAQ, but hasn't read these forums and hasn't been instructed by someone who has, that knows how to properly check target eligibility.
The overall change would speed up play, make it easier to understand, and allow for more firing, which I feel are all great. Wider firing arcs would also be more impressive, as they should be.
