Crystal farming and gatherers

[BobbinT]

So even if you're in a lv. 50 area farming shards, it wont count towards DoL reward?

I see you have above lvl 40 DoL classes. Best you open your achievement page in-game, then try farming shards yourself, and then check back achievement and see if your shard farming does count on other tier besides tier 1 achievements. That should clearly answer your own question.
