Can we just remove shards from the game?

[Ultimatecalibur]

What stats/level do our Miner/BTN retainers need to be to bring back 30 shards per venture? I have 4 of them (lv 42 ish) so being able to net 120 shards every 50min would be lovely

I know my level 40 Miner with Gathering 230/Perception 225 can get 30 shards after 40 minutes for 1 venture, but I know she reached 30 shards per venture early on and 40 minutes per venture sometime in her 20s. She can also get 30 Crystals in 50 minutes currently.

Check the Mining/Harvesting level 1-5 ventures and make sure you have checked that shard off in your gathering log.
