In an effort to help warlocks in their soul shard usage, one of the changes coming in the next patch has something to do with their Ritual of Summoning spell. In the pre-TBC days warlocks had to stockpile loads of soul shards to summon every member of the 40 man raids twho were not present. While the move to a smaller 25 man raid was a lot of help, what really made it easier for warlocks is shift to using meeting stones to summon people. This way any two members of the group could summon the whole party.
The new change coming to the Ritual of Summoning is in effect something from the pages of the Mage Ritual of Refreshment spell or the Warlock Ritual of Souls spell where a tangible object is summoned for the rest of the group to benefit. In the case of Ritual of Summoning, the warlock creates an object that acts like a meeting stone. For one shard, the warlock can summon the whole raid from anywhere where summoning is allowed. In fact, since it acts like a meeting stone the warlock doesn't even need to be there. H e just creates the object and can leave the summoning to the rest of the group present.
Just like Ritual of Refreshment frees the mage from having to do the hard work of conjuring so much water and trading it to the party, this new change to Ritual of Summoning frees the warlock from having to do so much clicking to summon people.
