I've seen the EA ulm PD shaman cast summon earthpower before.

I opened up a disassembler and hunted down the spell weighting function because I wanted to see what triggers use of the berserker spells, but it's a maze of crazy cases. The AI definitely isn't random in the least (ok I did say there was no random calls here but I've found a bit of randomization of the scores after their calculation, but it wouldn't cause any sort of trend), but the algorithms used are indeed questionable.
