i heard this now multiple times and ...why?
i could easily level from 100 to 110 without setting foot into my orderhall once, heck i leveled 3 toons only by invasion events. The only times you NEED to interact with it is to get your artifact weapon and to get the start quest for each zone.
The Start Quest for each Zone can be solved with a Quest Board. And the Artifact Weapon is not so different to any heirloom weapon, or just a random scaling Weapon for that time.
i leveled 13 characters to 110 so far. and it's not rare that my artifact level was only at 4 to 6. I did all the Orderhall Missions at 110, only on my main i visited the Orderhall every now and then while leveling.
