I'm fairly new to the metagame, but wouldn't those previously mentioned special cases normalize the values to some extent? Unless the 'freeze', 'delay', 'reverse time', and 'invert attack' effects aren't used very often, I would think that might be the case. -HP effects would be replaced by those effects when facing a higher HP creature in actual gameplay, so in my opinion, resilience would not increase so drastically from 5 to 6 HP. Could resilience against special effects be quantified?
Anyhow, I love this thread, it's an excellent idea.
