Most of the Rank 40 weapons were able to hit the 1.8M stat cap in their primary stats.
With Rank 41's now, it becomes even easier, right? Are they truly that superior if they both cap out at the same stat cap? --- One of the many fools who facepalmed after throwing a thief armed with a Magichanged Prinny.
Nope, if they both cap there's no difference (since you still have to put in the full set of bills to really cap it). The Baal Horn was better than the Baal Sword because it had high enough ATK to max and decent Int instead of the Baal Swords attack focus in the PS3 version.
I dunno what the rank 41 weapon stats are but things that could make them better are having more modifiers to non-capped stats, and having modifiers to things like range, move and jump (and to a lesser extent Crit since I'm sure everyone is using the appropriate innocent away).
