Considering there aren't many reasons to use Astral Flow these days, that BP could have some use.
Could like use it, then /convert and use Alexander or something? Easier recover from a wipe, I dunno, regardless it's a cool and originall BP.
The TP reducing one could be cool if the amount reduced is noticeable and if it works regardless of Sleep sticking.
The Amnesia one too can potentially be insanely powerful if it sticks with a decent rate on anything worth it (i.e. not EP monsters

)
Potentially even too powerful, up to the point it makes me think it will just be crap.
Overall yes, it's a bit disappointing maybe but I like the AoE Reraise, means I can just go /RDM without having to worry for RR items! xD Yai +1 for lazyness and stingyness.
