Yes, i said it and i can support this statement.
I just made a quick damage test on the dummies as handmaiden, only being on Heropower 650 without any power increasing talents, properties or traits. Here are the results:
Moonfire Bow unpowered charged body shot vs. infantry: 29.25 + 7 + 12 * 8.25 = 135.25 Damage
Moonfire Bow unpowered light body shot vs. infantry: 29.25 + 6 * 8.25 = 78.75 Damage
Moonfire Bow unpowered charged head shot vs. infantry: 50 + 7 + 12 * 8.25 = 156 Damage
Moonfire Bow unpowered light head shot vs. infantry: 50 + 6 * 8.25 = 99.5 Damage
Moonfire Bow unpowered charged body shot vs. armor: 14.75 + 1.75 + 12 * 4.25 = 67.5 Damage
Moonfire Bow unpowered light body shot vs. armor: 14.75 + 6 * 4.25 = 40.25 Damage
Moonfire Bow unpowered charged head shot vs. armor: 25 + 1.75 + 12 * 4.25 = 77.75 Damage
Moonfire Bow unpowered light head shot vs. armor: 25 + 6 * 4.25 = 50.5 Damage
Needless to say that the Moonfire Bow is able to kill every special on legend with a light attack body shot without the need to reach for any form of breakpoints. Same as with cata and charged body shots, though the light shot already does more than enough damage that surely a breakpoint for infantry specials can be reached even without going full into the build. Just for a little comparison, Waystalker needs 4 specific properties and 2 talents to even come to the point of oneshotting every special on legend with a charged body shot from the Longbow and that is already the highest she can go with one arrow.
Of course we could say that Moonfire Bow is limited, but 6 light shots or 4 charged shots are fairly enough for the majority of situations. No, i am going a little further here and say that Moonfire Bow is basically a Handgun with unlimited ammunition, no reload time and a small AoE. Moonfire Bow alone trivializes legend runs even in a newbies hand, it has almost no weakness. Its effective against infantry, armor, super armor and monster resistance. Its easily the best weapon in the game right now by a margin and only because its clearly overpowered.
I see the problem in the DoT. It usually does way more damage than the initial hit, almost around double the damage. That needs to be toned down. Moonfire has to be nerfed to the point that it needs to reach breakpoints to flourish on legend +. Right now the breakpoints are more of an unneeded joke, like killing stormvermin with one light body shot.
