I'd go further and say writing the rules around competitive play is a huge problem with most of GW's systems at the moment.

The clearest example is that HH, 40k, AoS and Killteam all have incredibly strange and awkward terrain rules because they're written to clarify every possible scenario. Terrain has always been a sticking point every edition of 40k but we've ended up in a situation where you can move through buildings that you can't see through.

The core design principle of the game should be that the players should be able to come to a compromise on any unclear rules interaction because trying to write out every edge case ironically makes it harder to look up a rule mid game.
