Interesting poll. I'll toss my hat in.

1. A
2. C, F, L (Carbuncle) - If more than 1 tier is added, SCH should learn tier 1.
3. A
4. A
5. A
6. A and B

Given that the post from the Dev team compared the spell to Counter, I don't think we'll receive a 100% effect. This spell has the potential to be very powerful. I would not mind a base 20% activation rate that could be increased based on enhancing or summoning skill. I also don't think that the spell should work with Accession even if it goes to SCH. The more people the spell is able to be cast on, the weaker the effect is going to be.
