As a fan of both of the things Sharp mentioned are bad, I nonetheless agree with and second what he said on both those things.
On a different note:
Instead of doing Target AGI vs Attacking Stat, the resource free version would be Half Target AGI vs Attacking Stat.
A successful resourceless dodge would allow you to avoid the damage as per standard dodge, but an unsuccessful resourceless dodge means taking full, unreduced damage (whereas standard dodge at least reduces the damage on a unsuccessful check).
It's simultaneously a more risky/dangerous option against unknown attacks and a more safe option against known weak attacks, and only suggested at all because enemy stats are supposed to be unknown to players (until possibly figured out).
'Monster' in this case just means really good at interruptions.
Also, I may have missed something when I mathed things out earlier (Do base stat points not count towards sync?), but I managed 5 Reactions a round when I was going through numbers (SPD was the same, but I didn't go pure AGI as a secondary, instead splitting between AGI and BRA until I hit 5 Reactions and putting the rest into ENR).
Gut feeling tells me it's either a specific power or a secret/undisclosed mechanic.
