It is but you can use green and yellow skills to reduce the initial lockdown. CD after use is 12.

Do you hit auto cap?
If so, press her 1 and that's another 80% more damage she does on echoes, which adds up to 240% extra damage on a TA. However, she has no utility besides an unreliable charm and delay, and no buff besides her echoes. You can abuse her third skill if you have Crimson Fingers or Egg Sex in your grid though
tl;dr Completely selfish auto attacker
Did you get anything good at least?

8 Omega modifiers is overkill no matter which way you cut it. At this point you might want to throw in another normal or EX modifier in the place of one or even two of the Zaghnals.
Luna's Friend >>14268906 mentioned would be a good start. I'd even go for another Bahamut weapon but a dagger would leave Narmaya with 30% less normal attack than the rest of your team. A better choice would be a Qilin weapon if you happen to have any from RotB. Last case scenario you can use a Hellward dagger from Cerberus's Showdown.
A GW dagger is always a good investment for any element unless you have a Flashfest or Legfest dagger (Parazonium for dark and Love Eternal for wind), a Hermanubis (Dark) or the Xeno Ifrit Scythe (fire), or already have a character that gives DATA on ougi.
You might want to skill level up Olivia's weapon and use that in your grid instead of one of your Zaghnals since that is a Normal II skill and has high chances of eventually being very good when FLB comes out. Don't spend any chocobars in it until that info comes out though, just use it as a normal modifier for your grid.
You might want to run motocal to check which weapons are worth replacing though.
As I said at the very end, you might want to check in motocal if it really is worth trading your axes for the other weapons I mentioned. I didn't do the math and I'm just speaking based on diminishing returns. Actually testing the grids on motocal might give you different results on what is worth keeping or replacing.
Also, even if you take them out of your grid now, you can save them for a dark stamina grid, since many raids are so CC'd you can't lose the HP you need to lose to make the claw grid work. Another option, as you pointed out yourself, is using them as skill fodder for Bahamut Weapons or seraphic weapons.
No restock, you only get one FLB.
