Two more things i want to mention:
5. Flurry of strikes. Maybe it is bug but normal dual weapon attack does same (or even more!) damage than Flurry. That's really weird.
6. Negative statuses. Most of the "soft" negative statuses' duration is 1 turn. By "soft" i mean statuses that do not prevent char from all actions - that is Atrophy, Silence, Blind, Cripple, Slow. Also want to mention Sleep 'cos you can't attack sleeping char without waking him up. Such a short duration makes these statuses too weak most of the time. In all my playthroughs i ignored them in 80% of cases because of it. And it is creating one more problem - Walk it off talent is totally useless because of it! Who would need it when most bad statuses' duration is 1 turn already? I think increasing duration will make these statuses more usefull and won't break game balance since you have many healing spells to remove them and Walk it off talent.
And one bug with Silence status worth to mention - it is blocking Bouncing shield ability.
