Is Mailbreaker a good holdover until Garuda's Gaze/Curtana?

[PArcher]

I don't see why not; looking at other swords its better than Ifrit's, especially if its HQ and melded, and Ifrit's is the min for Titan.

Just get a good shield to pair with it too.

EDIT: if you meld it right (and have HQ...if you have NQ you should get Garuda's), you don't even need to farm for Garuda's, just go straight to Titan and your Relic
