My build is:

STR 135
VIT 80
DEX 82
INT 17
MND 80
PIE 80

Like i said in another topic here, i use a balanced allotment, with spike in STR and convertion traits depending of the class.

As actions, i had the basic attacks, maim, skull sunder and brutal swing equipped for single target, brandish and storm path for AoE combat and both foresight retaliation set, defender, bloodbath and warmonger for tanking.

From cross-class i use ARC boosts for Maim, absorb spells for better performance, siphon TP and MP, Sac3 and cure2. Also have second wind and barbs.

But this build was prior 1.18 so i can asure you its not really working properly anymore. Right now i believe low TP cost WSs, feint and invigorate might be needed for improved TP generation due its current obscene long delay, also adding featherfoot retaliation set for better defense and another extra cheap WS is good too.
