To those complaining about the changes:
Thanks for making professions obsolete
In no way does this make professions obsolete. There is a cap on JP and, unless you were running dungeons nonstop while leveling, it is very doubtful that you have enough to buy more than one or two pieces of gear. If you're clever, you'll be buying items that cannot be crafted by your profession.
Thanks for making scenarios obsolete
Scenarios don't even have a guaranteed item drop. On top of that, if you are fortunate enough to get an item, they ilevel is 463, just like heroics.
I had the ilevel to get into heroics right when I hit level 90.
Congratulations. Not everyone did. Not everyone will. That's not a reflection of skill. It's a reflection of luck. Dungeon bosses dropped the loot you needed, you happened to find rare mobs who happened to drop items you were able to use. You happened to get enough Motes of Harmony to make enough Spirits of Harmony to buy the patterns you needed.
This was an unnecessary change
The JP gear from AC, GL and SP would have been obsolete before it was even purchasable thanks to the slow daily progression and the Golden Lotus gating in place.
On top of that, not everyone will want to grind dailies every day. I certainly won't be on many, if any, of my alts.
This speeds things up too quickly
In what way? People were going to get into heroics fairly quickly anyway, either through farming the needed Spirits of Harmony, purchasing gear off the AH, targeting questlines that gave an upgrade or running normal dungeons.
I reiterate: had this change not gone into effect, the JP gear would have been obsolete before it was even purchasable.
This makes factions obsolete
In what way? You still need to grind to get VP gear and vanity items.
On the subject of the JP gear itself:
I am in agreement with those who believe the JP gear should be ilevel 463, or have the option of an upgrade to 463 either with a Spirit of Harmony or through an additional gold/JP purchase.
In the past, JP gear has been equal to heroic gear and acted as a supplement to gearing—very useful for those who were having a difficult time getting a boss or two to drop specific items, or who were finding their items snagged by others.
The dailies served as a gate and by gating the content you'll make the most of the expansion. The problem is with how people think, they need to have the content done in a month which will lead to rushed progression. That's how FL happened and DS happened, those were both downed within the first week on normal mode. And don't give the the whole "Fights should be easy normal mode and hard on heroic" excuse, this game should enforce normal modes being a wall because it slows down people thinking the sole purpose is to steamroll the content in a week and whine for newer stuff.
Blizzard makes content accessible and doable for anyone, it gets done in a month or two then they're whining for new content, well the next tier gets rushed and people are whining they can't do the heroic modes, those too get nerfed then everyone has it done, now everyone wants ANOTHER tier. All of the content of Cata was done within a year and DS was stretched from mid November to the release of MoP. And FL lasted a grand total of maybe four months.
There's a reason BC was better, and it was because Blizzard wasn't afraid to enforce a gate on people. Kael was in BC on release, he wasn't downed until four and a half months into it. A majority of the community was floating around early/mid SSC by the time Nihilum had Kael dead (And they had Vashj down a month prior) and by early SSC I mean attempts on Hydross but Lurker on farm. (Everyone had Lurker on farm though, he wasn't hard.) They enforced requirements and THAT happened, where they didn't need to rush content.
I ran each dungeon ONCE when I was 85, and each once at 87, I got ONE item that wasn't even for me but I took it because we had a paladin healer and no other clothie, despite the fact it had spirit. And when I leveled I had a 440 item level and it isn't hard to run a scenario. I did the Arena of Anguish, BAM, amazing staff. And it isn't hard to purchase contender's items to replace a few greens of 410 quality. Or a Ghost Iron Dragonling. The problem is people perceive their lack of gear as lack of ability to get it. Solutions are everywhere, people are just too dumb to look for them.
And you're also avoiding the possibility of Blizzard doing what they did in Cata and making previous valour gear JP purchased. So leveling the reputations wouldn't make the gear obsolete, you're investing the in the future. You live too much in the present and that's a very big problem. And you also cited bad luck to counter the argument of "440 Ilvl isn't hard to get, I had it when I leveled." Well that argument is flawed left and right so I'm not even wasting my time to prove why you're wrong.
