How many whacks does it take you to drop the ruler with that 775K of melee? What damage are you hitting in PvP or PvE?
Showing anything over +32k melee seems a bit dodgy however I am not sure if PW started displaying attack and defense using long ints (32 bit) or are still showing short ints (16 bit).
Here's a quick fraps of something to give you an idea of what less than half of that can do:

To do that I did some heavy database editing in a local test server to set int & str to 10K each with a 100% all attack mace. It gave me just under 200K melee (wrapped 3 times) all told.
I think I'll send your screen shot into PWI to see if they can explain how it even
remotely possible to have 775k melee in this game without hacking.
It will be interesting to see what they have to say about that. It is a good thing you left your char name on there.
