While leveling some alts 100-110 I’m forced into the legion artifact weapon chain after completion i notice even though I am <110 the Weapons abilities have all been disabled. why force the quest chain on people for a subpar item 
Also I am guessing the time walking vendor will no longer be selling the heirloom upgrades or will they still continue to have levels even though they don’t provide XP benefits ?
Will a person with a level 80 Heirloom cap have the same set bonuses and benefits of that of someone who has maxxed heirlooms?
The Legion artifacts mostly got their powers from pruning abilities from the classes. Just like the Draenic perks (90-100, every even level) added back pruned abilities.
At the end of Legion, they again reshuffled class abilities, and put the Artifact powers back into the classes (more or less).
You can still get the relics to increase your iLvl, but aside from that, they are only for xmog (including the skins you unlock).
The only artifact that kept its abilities was the fishing artifact.
And I’m hoping that, with the level, stat, and iLvl squishes, and with the XP bonus being gone, heirlooms will have only two levels: 1-50 and 50-60.
Because there is no Weapon Drops for Legion. Not everyone has heirlooms, and shouldn’t have to go buy them so they aren’t stuck using the previous xpacs weapons. You can also transmog the Artifact skins you unlock.
I don’t understand why it’s such a big deal to you that an expansion that only has one weapon is having you do the quests for it. There is no reason for them to completely change old content that revolved around that system just because people don’t want to do it because they have heirloom weapons instead. The Class Halls and it’s quests are tied in with that system. It’s easier to disable the traits then to dismantle the whole system and make new weapons drops and untether the quests from the artifact and class hall.
you get a tonne of exp from doing the super easy artifact wep chain
It’s fine to disable the trait instead of breaking the stale outdated content , i just think the weapon could be more rewarding and not be less appealing than the existing heirloom weapon. I guess having my staff talk to me on occasion should make me warm and fuzzy inside. if what Im reading the SL questline crunch will also have an affect on this ?
as far Ton of XP for quests ,
A ton is relative , in the same amount of time I could get a higher XP per Hour burning through quests and or assaults with full heirlooms.
I think they should put a few basic weapons on sale from the class hall quartermaster. The only weapons that drop in Legion are some in Argus that are intended to be cosmetic and a couple in Antorus that are rare.
There are, actually. They’re meant for use by off specs so you have something to use until you got the Artifact.
I am still trying to get that truthguard withered training skin. shakes fist Give me that hidden skin you stingy withered!
