To be fair, the only part that really applies to the term "simulation" is the battle instance. As others have agreed, the wave physics in storms are one of the best demonstrations of that feat. The open world is more game, and less simulation, but it still ensures that storms are rare, and battles in them are rarer still.
Let the devs create all of the scenarios. The whole point of a simulation is to give you realistic choices. It's our jobs to choose if we want to risk fighting in a storm.
Btw, lol, have you tried hitting anything in a storm instance? You make it sound like the game makes it easy. I assure you, it's no WoWs.
