I figured one thing out: No one is really prepared for surprises in LD. And since the extra explosion spikes are like blast cube balls, they don't have a blast radius HAI THAR I AM A BOMB thing, plus the unknown fuse count, which could make less attention-paying enemies successfully die from the shards BOTH in LD and in PVE (duh, the only enemy that actually is intelligent is a gremlin)
Discuss how much the new shard bombs can be field traps or not.
I was going to defend shard bombs a bunch but then I saw Lockdown.
Yup, they're useless.
