I have always played my games away from home, and as I cycle or skate everywhere, I have always built my models with a strong consideration for how to pack them safely and efficiently in a rucsac.
I use KR cases, but also a variety of smaller card boxes such as iPhone boxes, cigar boxes etc..
I build my models to avoid outstretched arms, oversized wings etc, to reduce breakage and to allow tighter foam configurations,
My core army has 4 Raider/Ravs, 3 Venoms and all the infantry, around 1200pts, in a single KR case, as my vehicles have no sails, no spikes, no chains, no trophy spikes. I actually prefer this aesthetic anyway.
When I started this army, in 5th, the BRB specifically stated that decor, limbs, wings etc were NOT considered part of the model for Line Of Sight purposes, so this simpler, more compact form was no problem.
I even declared to my opponents that I classed the rudder and the pointy prow as "not part of the model, but decor", which reduced the disembarkation and open-topped firing footprint, but made them easier to hide; a fair trade-off.
9th, and I think 8th, no longer state that rule about models only counting as their hulls and torsos. if you can see a wingtip, banner tassle or the very end of a tentacle, you can shoot them to death.
As such, are my Raiders now built for advantage? They are easier to hide as they don't have their sails and masts.
I could easily change my attitudes to rudders and prows, obviously, I just have to remind myself and my regular opponents.
Whilst we are the most powerful codex on the block (allegedly!) I am very keen to ensure I am not taking further advantage in the light of what is effectively a rule change for me.
