Just making Nature and Religion get bonus from having high Wisdom doesn't necessarily mean that your char is gonna be automatically good at everything, there are lot of different skill checks. Dunno how you come up with these conclussions. It just makes more sense for the Druid and Ranger classes or Priest in the case of Religion.
What do you think is happening when you make a Nature check or a Religion check? What is the difference between Nature and Survival? What exactly are you checking and what does it have to do with Wisdom? How would you explain the difference, mechanically, between a Druid that is good at their job and one that is bad at it?
Those who disagree with you in this thread have given some pretty solid reasons for why things are the way they are. All you've done to support your claim is say that it's obvious that it should be that way (it isn't).
We even have a 18 int cheat item very early already. Even if you don't agree because this doesn't stick to 5e you have like a million other things that completely mess up the game in crazy ways and don't have anything to do with 5e at all.
Both of these points are irrelevant to the discussion at hand. Of course there are other problems with this game - that doesn't in any way support your claim here.
