Few questions on Character card deck system

[Raul]

Unfortunately Character Cards aren't shared across merged worlds. Lv120 Cygnus weeps in a merged server on my account.

Dammit.
Is there anything that's shared across merged worlds?
I feel like there's something, I just don't remember what.

Sorry about reviving an old thread; I just thought this question does not deserve its own thread:

Does Mechanic's buff apply to Final Cut?

If it does...

Final Cut (w/ decent combat order): Duration & Cool down = 60 & 88 seconds
200 Mech (+20% buff duration) + 120 Mech (+15% buff duration) + 120 Mercedes (4% cool down reduction) + 120 Mercedes: 81 & 81 seconds
