I suspect I am a quiet voice alone here. The changes in D&D from 1st edition to 5th edition are significant, but for me, one of the big ones that I really like is that, despite having most of the same magic items, you don't really meet that many - the 'power' of the game is with the players, not their items. But the limitations of the characters make the party make-up important, and teamwork is particularly important when different characters have the different skills needed to meet the challenges thrown at them.
For me, this change is the slow slide of the game to becoming unbalanced. It is the equivalent of a TV show having to have 'Special Guest Stars' because it is not considered as popular any more. This change for D&D will move towards another change and split the community I fear.
Further (phew!), I worry it is driven by the need to keep selling books. If so, Wizards need to open their eyes to the fact that their world is not just the Sword Coast - there is a massive continent for us to explore and there must be the potential for literally 100s of adventures across its landscape - something of course, that has been noticed by others,
I would not like to embrace these changes ... the limitations of the characters are part of the game (apart from the fact that I do feel a little sorry for the Ranger).
