You never will.
The less effort something takes, the less valuable you find it.
A heavy restriction will have you making a Fire Sorcerer who focuses on burn damage, that utilizes the Frost Bolt enchant to cause chill to slow enemies for defense. A light restriction has you making a Sorcerer for whatever - it doesn’t matter as none of the decisions you make hold any weight. You are far more invested and interested in your Fire Sorcerer who is looking for very specific gear. Your EZ Respec Sorcerer is whatever you pick up - you don’t care because no decision has any weight.
“But you don’t have to respec” is an argument that falls flat on its face. The game is designed for how easily you respec. If they try to design a game with EZ Respec, but with the challenge of a heavily restricted respec, the game will be far too easy for the people who min-max each challenge.
They have taken a middle ground. You can’t constantly respec all day, but it’s cheap enough to change aspects of your build daily.
