The trooper has almost certainly been forced to declare Change Facing at the point the mine gets deployed next to them, unfortunately. The jumping for cover moment is when you try to Dodge the mine exploding - presumably there's no 'arming time' to take advantage of or something.
Not in the situation we're talking about considering how you climb in this game, but in the general case I find it annoying how impotent units are when a Mine Dispenser or Repeater lands literally at their feet
in this case, as the climbing model has to reach to the edge, there will be LoF from any miniature deployed on the roof (facing in that direction)
Seconding this. I find launched deployables more frustrating than tactical, would like it if people could respond to a deployable (or at least a "fired" deployable) appearing in LoS.
I think at this point all we can do on the overall discussion is agree to disagree, but this bit appears to be misunderstanding/misremembering the situation. Only troopers with Climbing Plus can lay Mines while on the wall, so yes a Change Facing ARO is almost guaranteed to have been declared, in response to the active trooper declaring Move or Idle.
If the enemy has their back turned, has additional obstacles, or is situated on a different level - sure. But if the enemy is turned towards the enemy trooper and is standing on the same level, there will be LOF or reciprocal LOF given your own interpretation of how the mine layer is placing things over the edge. But yes, we should agree to disagree. This is an edge* case and I'd argue one should always err on the side of caution considering how damaging springing obscure tactics can be to player-to-player trust. Hopefully N4 rules will be better at clarifying edge* cases. (* I mean, cases where the rules become unclear due to conflicting rules or complicated situations, not only cases involving literal edges) Post was edited to moderate tone a bit
I'm pretty sure Whyrocknodie's diagram is supposed to be representing a trooper that has their back turned. If they are facing the edge I agree with you completely.
I think N4 should have a boxed out 'rule' in the first page that reads: " 'screw it, that's close enough' When we say a situation requires base/silhouette contact there are times when the human eye and hand cannot determine a perfect resolution for model placement (or the dynamic poses of two models prevent proper base contact at certain angles) as long as the full base/silhouette fits in its intended location then both players should move on and play around the minor inconvenience of micron level geometry. Note that this only applies to base/silhouette contact with another base/silhouette. " (delete the last line if CB decides that intent play is acceptable on general principle rather than in specific circumstances to make the game playable)
Yes, there should be LOF as long as they're facing you and there's no rooftop cover to potentially block LOF. This does not prevent Change Facing ARO shenanigans, however. I can totally see a Zhencha drop Stealth to Climbing+ up the side of a building and lay a mine on the roof to frag whatever was standing on top there.
