It is all acedemic. In PvE, our Soul Shards will be used to Demon Soul once every 2 minutes; there are few fights we get more than 2 of those in anyway so the extra shard will likely be a utility 'spare'.Originally Posted by Blizzard Entertainment
Frankly, I'm very disapointed - there was a lot of potential there for the new Soul Shard system yet for PvE they've attached it to Demon Soul as a cop-out to balance the limited use, by presenting us with a single use for it thus reducing it to no more than the 2 min DPS cooldown everyone else has. Yawntastic.
