We seem to want two contradictory things - dynamically posed models with lots of options for weapons, and models optimized for the rules.
Hello! Welcome to the forum (if you’ve not already been greeted)!
The bit quoted is a good point. It comes into play with TLoS and WYSIWYG.
We all love cool Miniatures and scenery, though there’s often an element of what is practical vs. What has to be abstracted for a game.
A 100% realistic forest is great! But difficult to actually put models in. Likewise a beautifully sculpted mountain offers balance issues and more appropriately a dense underhive can be difficult to actually get access to the middle.
I tend to think of Miniatures as the avatar for the character, who would otherwise be a living, breathing individual. However I don’t expect them to be swapped every move to a more appropriate pose for the situation they find themselves in.
Other games don’t really have this problem when they
don’t expect the real world to exist side by side with the in-universe game world.
So a board game for example (generally) doesn’t have this issue. All the rules and mechanics are located in the context of the game - they’re not suddenly expecting you to work with things outside of the mechanics. Like actual appearance of the model, their kit, or what they can see.
Necromunda is a hybrid of real life and virtual and these things require either compromise by players or strict rules in how to interact with actual real world objects other than the subjective “can you actually see it?”. It’s not like we’re firing matchsticks at each other’s models, the shooting phase is abstracted to game mechanics but the targeting is not.
If you want cool dynamic models, maybe the rules need to be a tight as possible to the point that they ignore the actual physical look of the Miniature? If you want more relaxed rules then the models need to reflect the fact that they have to be adaptable to the actual physical environment they’re put in.
They really should partner to make LEGOmunda. It’d help solve a lot of these WYSIWYG/TLoS issues because you can literally pose and equip the models as you wish!
TL : DR They’re wanting you to play nice so they don’t have to write a whole load of rules to deal with an almost infinite variety of scenery you might encounter.
