Duelle, I understand that you're trying to make points by comparing stuff in FFXI to stuff in other MMORPGs, but I think gaining a better understanding of what stuff in FFXI actually does would be a better approach.

Paralyze can't prevent a monster's TP moves, so it's drastically different than all of those abilities you compared it to. In fact, it can't even prevent a player's weapon skills.

There is an accuracy down spell. It's called Blind. There are two tiers of it, with the second tier being a Category II merit for reasons no sane man will ever grasp. It's sometimes useful, but the hardest monsters have huge amounts of accuracy so it just changes their hit rate from 95% to 95%.

I guess you're referring to accuracy and evasion down spells that would work on a percentage with no chance of resist, similar to Dia and Bio? If that's the case, I agree something like that would be nice.
