do you BELIEVE or NOT in time affected drops

[K_I_R_E_E_K]

I do find it odd myself:
After playing the vhard forest with a viridia and a bluefull for nearly a week straight just trying to get a yamato, I eventually gave up and decided to hunt something else.
A soul banish and a Twin Chakram. So, I made a RAcast, skyly, for the soul banish and my lady made a fomarl of the Oran sort. We got both of them to Vhard, and on the first run for BOTH of them, they found a yamato. Now, excuse me, but their drop rate from the vhard dragon is no different from bluefull or viridia.
What the piss?

Musashi did a similar thing to me with said bluefull and viridia. When I first went to hard, long, long ago, I found about three musashi. But if I take any characters through there now, including those viridias and bluefulls (usually just to test certain things), I don't see the musashi anymore.
What the piss?

those things must piss you off for real, talk about bad luck.
