- Drain Soul: Each time Drain Soul deals damage to a target which can grant experience, it now has a chance to generate a Soul Shard.
- Soul Shard: This item now has a maximum count of 32 in inventory.
This change is not yet on the test realms, so I have no first hand knowledge of how it will actually function. Fortunately, Ghostcrawler elaborated on what it will be like. Based on his commentary, it appears that this change is designed to keep warlocks from needing to meekly inform the raid leader that -- after so many wipes -- they need to head down to Dragonblight for some shard farming if they're to continue summoning pets and health stones.
Given the obtuse nature of this infernal reagent, I'm surprised this change was so long in coming. Warlocks have been complaining about how difficult it is to manage soul shards since before I rolled my first 'lock. I'm looking forward to seeing this change up on the PTR, where I can get a better idea of just how awesome it's going to be.
Updated: There's been a lot of talk about this being an unsatisfactory change to the soul shard situation. I think it's important to note that Ghostcrawler mentioned two changes would be coming for drain soul. One will be a very large change that will significantly alter gameplay, and the other is more of a minor tweak. A stopgap measure while the larger change is worked on. I think it's safe to say that the above changes announced for 3.1 fall into the latter category, and we can look forward to more significant alterations later on.
