I'm currently stuck in a vacuum between normal 5-mans and heroic 5-mans because I can't afford to buy BOE gear. I managed to burn to level 100 by doing dungeons, because "kill x <NPC> and gather y amount of <item>" quests got boring nine years ago, but you can't reach ilevel 600 through dungeon running alone -- the final dungeon only rewards armor, not accessories or weapons. You need to either do Nagrand quests until you get some ilevel 600 gear, or grind follower quests ad nauseam, neither of which I have any interest in doing.
It'd take you all of a couple hours to do some questing in Nagrand, if even that.
Choosing not to do a major facet of PvE and then talking about how you can't progress in PvE because you purposefully skipped content is not a game design problem.
What about Follower Missions? You do realize that you can get a 615-645 weapon/OH + Shoulders/Body/Trinket/Bracers/Boots out of Follower Missions, right? Of course you'd have to do some... *gasp* questing to unlock followers, but the rewards are ridiculously awesome if you did. Just an hour a day and you'd eventually make it through the main questline in each zone and probably get your 20 followers that way. Or, you know, just build an Inn and recruit 1 follower a week though that'd take months to build a full group of 20.
The 615s only require Lv100 followers which takes... what, a week of doing the missions twice daily? It takes maybe 5 minutes to log on, collect missions, then send followers out on new missions and you only need to do that morning&evening. Make sure you get the Master Plan Addon which makes it easier, though (hopefully sometime Blizz will update their official UI to make it less painful). My Blacksmith
hasn't touched Nagrand whatsoever beyond the first few intro quests (she doesn't even have the outpost building yet) and she's 633 just from Follower Mission items. She's not wearing a single BoE. She is wearing a total of 2 items that didn't come from follower missions: The Legendary Ring (first step, only requires clearing 1 dungeon) and a ring you find just laying around in Nagrand (no quests required to get it). Everything else she's wearing is all Follower Missions and Salvage Crates gotten from Follower Missions.
Also, don't forget that you can buy 630s with Apexis Shards, with the Missives you can buy for 200 garrison resources each. It takes about an hour to get enough Apexis Crystals to buy 1 piece of 630. Who needs crafting BoEs when you can spend one hour to buy comparable gear from the Apexis Trader? Heck, who needs RNG Heroics at that point, 'cept for weapon and jewelry?
EDIT: The Salvage Yard can also give you 610 items in the Weapon, Off-hand, Legs, Helmet, Belt, and Cape. Edited, Mar 5th 2015 7:40am by Lyrailis
