Not so much of a full build, just something I've been experimenting with over the last week.
Full combat feats, but taking the shift-cooldown reduction (first column combat lower) instead of 5% lifesteal, plus every boon for stamina regain in combat, stam regain jewelry kits, and a trans elven battle. I think 2 of my artifacts have +600 stam regain too. Gladiators guile, artificers, and splitstrike feated on main hand.
Anyway, results: cons, loss of 5% LS, but since I'm not a lifesteal build in PvP, nada. Pros, ability to shift like crazy pretty much all the time, and considerably shorter cooldowns on PG, boars and Fox. I can knock maybe 5 or 6 seconds or more off each, and also accidently dodge a lot of hits while I'm shifting around.
