I've been meaning to look into the specific Pheonix dynamics of this for a bit, so thanks for the thread.
I'm particularly interested in Animst Verdant bladeturn bomber versus Warden PBT, as I play both classes.
1. Does this apply only to PBT bladeturns, or any bladeturns? (The thread implies just PBT, but verifying) 2. Does the immunity window occur from the moment the bladeturn lands, or the moment it's broken? (Thread implies moment it lands, but verifying)
Either way, it makes even a 2-PBTer stack of 6s pulses unreliable, as the timing would have to be perfect for every other chant to not land during the immunity phase. 2s immunity seems a more reasonable compromise.
