Exactly. They have become even more critical then before even if one of their primary uses is now shafted a bit. Without Daydreams, all those list have very large flaws to them and are a lot slower then they could be.
What the Daydreams did for the Crew (ie not the Dreamer/LCB) has not been effected by the Errata/cuddle. Instead, what they did for the Dreamer & more specifically LCB has been heavily effected. They can still pull off a long bomb strategy and many of the pre-existing play styles are still intact, they just carry a heavier cost now then they did before.
But the perception shift is the real kicker here. Because his previous best strategy (long bomb) is now a little slower and more costly, it makes strategies focused around his crew a lot more favorable. To say that Daydreams were not an integral part of this is basically madness. Their roll and responsability has grown as any list focusing on his crew will require about 2 of these little buggers to maxamize his mechanics and the potential speed of the crew.
So as my mantra has always been, you want Daydreams with the Dreamer. Hands down, they are the best use of your SS/totem slot.
