Doomguard worth the shard?

[Xandy]

Pretty simple question, based on the results I've seen I'm questioning it's usefulness at all. Is it even worth a shard? In what situation would you say it is or is not worth a shard? Or should I stop complaining and just hit the stupid button?

as demonology when using Synergy, doomguard is worth that shard, should test for other specs/talents

For an instant cast, Summon Doomguard has a very high damage per shard cost. So yes.

fair enough, i wasn't sure if it's worth it on the pull i.e. use pull CDs for as much personal burn as destro and wait till after the opener to spend excess shards on it or something like that
