After a few games I think by my self so why do they switch
Wisdom for Memory in basic D&D Wisdom gives +1 resist + one (skill in memory)

So why did they not go with the traditional consider all other attribute are traditional after all and wisdom would have fine in this game.

My theory,
They thought D&D rules would be to old school and they not like to look old their for given basic old for the new *-1 resistance a point*
