I came back after a little break and am surprised to see a fair amount of shard bomb threads.

Here's why the shard bomb was removed.

Nick's ex gf told him the idea of the shard bombs but then in 2012 she called him and Nick got mad.... of course he immediately told OOO to remove the shards and change them so Nick could forget his ex gf.

All jokes aside I think the old shards should be put in as a rare item like Darkfang Shield and slightly changed from the previous mechanics but overall having the same game play as they previously had.
