Oh thanks for the info Hiko. The second link hits on a rather staggering factor I stupidly never thought of, and that is my distance from the target. Naturally, taking the time to run out 10 paces and back just for the WS is a waste of time. Goes without saying. But it mentions simply standing at max melee range so you do attack constantly but still receive a portion of the ranged effect has a smaller, yet substantial effect on the over-all damage. I'll have to ensure I note that point.
One thing I've noticed though, is that each of these posts give reference to the Amano+Yoichi combo. I feel like I'm missing a crucial factor here. To me, the OA2-4 Magian GK is vastly superior in terms of WS frequency. So much so, that if I pause for even a few seconds I could find myself at 150+TP (Sometimes do anyway, going from 80% into a 4 hit). In my mind, I think that if the above players used a OA2-4 Magian GK over Amano, the damage from the added Namas Arrows would override the melee damage from Amano. Again, that is how my mind sees it and numbers are not necessarily my strong-suit.
