In that same token, John, why does it have to be necessary that you bush kite?
Starting the game with no melee skills and meeting a group of zombies (or even worse a pack of zombie dogs) in your first venture two towns is already a nope your character is screwed moment.
Why is it a bad thing that the game has “nope, your character is screwed” moments? Those are what make the game interesting, they’re what provide the learning experiences for your next playthrough. That’s what roguelikes are all about. And you shouldn’t be able to handle a group of zombies on your first day.
Besides, a change to move cost 200 for shrubs still provides a tactical advantage, just not as big of one as with 400. I can get up to 5 hits off on a shrubbed zombie before they have a chance to do a single hit.
Throwing rocks actually is a pretty viable strategy to whittling down zombies early on, so that you can finish them off in melee. Changing shrub movement shouldn’t affect that.
Maybe you shouldn’t be expected to fight a horde of zombies your first day? Maybe you should be able to run past and lose most of them in a mad dash to grab the supplies you think are the most useful, if that’s the strategy you choose. And it is possible to find almost all essential supplies for a short while without going into town. Scientist corpses always have water. Military corpses sometimes have MREs. Berries and apples and other wild fruit are readily available. Gas stations spawn abandoned and outside of towns with food and drink, and occasionally other goodies, and even nearby vehicles that are usually in good repair.
Also, I play all the time with only 6 starting points and no debug menu. Though I almost always pick quick, that is an OP trait if ever there was one.
