Criteria: character creation >= 1/1/2011 and PKW >= 75 and PK% >= 50% and rank at deletion >= 48 (i.e. two legacies).
Should be noted that a few of these had PK% around 60%. That's enough deaths to frustrate many people, even though they were also getting kills.
In descending order by PKW:
Eleagra, Fire, Empire, Sword/Mace, Crashing/Greeting
Grafacut, Fire, Outlander, Dagger/Whip, Crashing/Greeting
Kurbrawn, Fire, Empire, Sword/H2H, Cry/Harmonious/Fires. One of those given as a reward, but I can't tell which from the PBF; will assume Fires.
Kaer, Fire, Outlander, Sword/Whip, Cry/Greeting
Karkarrak, Fire, Battle, Sword/Whip, Gates/Greeting
Aoirse, Cloud, Battle, Axe/Polearm, Riddle/Trapping
Zarkyem, Fire, Battle, Sword/Pole, Greeting/Landslide
Jikahl, Cloud, Battle, Sword/Axe, Crashing/Gates
Panitorop, Fire, Outlander, Sword/Axe, Cry/Gates
Updated popularity of weapons and legacies:
Weapons
======
Sword: 7
Axe & Whip (tie): 3
Polearm: 2
H2H & Mace & Dagger (tie): 1
Legacies
======
Greeting: 5
Crashing & Cry & Gates (tie): 3
Harmonious & Riddle & Landslide & Trapping (tie): 1
So the cookie cutter would definitely have Sword as a spec, and either Axe or Whip as second spec. He would definitely have Greeting as a legacy, then either Crashing, Cry or Gates as second legacy.
Of the 9 characters surveyed, though, only Kaer and Karkarrak actually fit that mold.
