Looking it up, it's actually 40 since Trapinch can have Hyper Cutter. So the situation really isn't that dire. Then again, Dugtrio have very high Speed, so it's possible you won't be able to escape the battle regardless of ability. Nevertheless, being thrown into battles isn't very fun even if you can escape them. Also, thankfully the Badlands don't have Sandstorm weather, it just really looks that way.Not quite; we often forget because it's bad but Dugtrio can also have Sand Veil -- so it's more a 60% chance. Still really atrocious tho.
Still a pretty botched implementation, though. And I agree it makes no sense that named Routes and background objects were dropped after XY. I know Game Freak tries the old excuse of "We want every game to feel unique", but the rest of their business model suggests a game is completely obsolete each time the next one is released. There is no need to make concessions to previous games, to not implement their popular features in any future games just to keep their gimmicks unique. For instance, there's no reason for dynamic background music to be unique to the Gen V games, it's not like Nintendo depends on those games retaining it as a sales gimmick eigth years and two console generations after their release. It could easily have been a mainstay of the Pokémon games by now, but Game Freak apparently didn't want to bother with the hassle for longer than they had to. It doesn't give a very flattering impression of the studio, as if they refuse to take any lessons and begin every generation with the fresh Gen I template, instead of actually building on the innovations they have presented over the years to make every game a bit better than the previous one.
