Players have been advocating doing something like this to help the new players and new toons be able to bridge the gap with AAs. Making a toon and then having to have it sit around as you can only do solo instances or non god slayer ones which rarely occur as it's more beneficial to be doing the GS mode isn't fun for someone who has alts they can use, if it's you're only toon then that would be very off putting for a lot of people to keep playing this game.
80 Expertise points are irrelevant to my toons as I've been playing since launch myself, but 80 points to a fresh toon or someone new to the game is good for me as well. It does benefit me as it is opening up the number of players than can do 6 mans as they have the major AAs that they need (providing they get advice on which ones to get). I'm not sure how this change can be seen as bad.
