I would put the onus less on "Dreamer Grief" and more on "Book 2 Grief". Kirai, Hamelin, Dreamer, Collette, they all have the reputation of being more than a little bent. The only faction that didn't benefit from the Book 2 power shift is Guild (though Hoffman is fun and cool, he doesn't rank). The majority of Book 2 masters overshadow most of their Book 1 counterparts in terms of overall utility, speed, lethality and value per soulstone (minion-wise).
Disclaimer: This is my opinion and only my opinion.
But meh. I don't want to turn this into "Another One of Those Threads". You either decide to play Chompy in all his glory or you don't. Some opponents will give you grief, some will enjoy the challenge.
