Yeah lauren is right ,in PVE , you need that swayed attention make more agro so mobs focus on you while in pt . I suggest taking cruel focus from dual sword buff , 5% attackspeed is worth , take only 1 . and take that shield slam on fighter tanker job , it good both pvp and pve . stun mobs or ppl is good you know
Last from me , take that Divine Intervension from templar skill , 5 second imune is helping you to hold alot of mobs
for how to play as tank , you can ask Lauren there to teach you xD
