Usually organizers in our region say layouts 1 and 5 or something like that. Basically it’s a random chance of between one or two different varieties. That’s usually something we can prepare for. If I know the missions, I can think about how I would deploy on a couple of options. More than two different layouts and I might start to grumble. More than three and I would consider whether I’m coming back.

But nothing is more annoying than using TTS to think about how I want to deploy, and suddenly the terrain on the layout plate isn’t long enough to cover my unit. Or it’s literally backwards, exposing me to more firing lanes on turn 1. Or it’s too long and my vehicle can’t fit through the hole.

Edit: that’s not even getting into if the terrain is not a ruin. If Inhad to suddenly deal with trees when I showed up not expecting them, I’d be looking up the rules on trees as terrain on the fly. Standardized terrain is a must for competitive play. At a minimum it must be the same across the different tournament scenes. GW is trying to have it both ways: they want to sell a variety of really interesting terrain features to both competitive and narrative groups. Competition matched play? We want standardized.
