Well I'm still trying to farm and see what gears drop in the new dungeon (namely from the highest leveled enemies). While I seem to be the unluckiest person in the world for armor I have a super good weapon and accessory.
Weapon has a drawback of -50% life, -4 skill point and -3 recovery but my crit POWER is 529% right now. My armor is only purple since I'm not finding anything yet that beats a Sagittarius Form. So right now if I didn't use item drop rate boosting gears I have a 42% chance of doing 529% (found a second one that brings it closer to 600%) damage. Take that you stupid armor enemies.
End result of the run: 49% crit chance, 584% crit power. That is about 4,600~ damage with just a regular attack when triggered. I have 960 attack with this setup. Only 6 skill orbs though at 15 recovery.

Level 99 Remilia can or should have 2500~3300 attack power, the lower end being a critical build weapon. Flandre even with triple health can be downed in under a minute.
