While this is a good idea, the number 1 reason why SE will not do this is

Progression.

If you make content easier to progress into, players will clear it faster. and get bored. then complain that content is too easy or there isnt enough.

Thus players quiting the game sooner, loss of revenue. Losing money is bad.

Its the same reason as why there are lock-outs on almost all top tier content, gates to slow players progression down to keep them playing, and paying longer.
