2nd Hector: DC or merge

I have one extra LA Hector, so I've thought on give DC to any hero, but I don't have idea of which hero is a good choice. I've thought on:

- Myrrh +2 (+Atk -Res), which has Fury.
- Effie +7 (+Atk -Spd), Has Death Blow + Brave Lance+
- Fae (+Spd -HP), has Fury and Light Breath refined. Another idea was Warding breath and Lightning breath+ for her.

And the final option is merge to my LA Hector +1, which improve his attack. Really, I'm not son convinced about give DC, what do you think?
