not for lvl 45 but..
full vit
taunt maxed
proc stance maxed
defensive formation maxed
shield bash to the lvl needed (37 is up to 190)
rest in shield wall (which can easily be maxed)
all extra pts besides that, warcry, enduring guard totaly not worth it, and leave the other dps skills for those who arent full tanks yet
for a full tank id say yes get enduring guard and also to get the best lux shield there is
but you definitely dont wanna go full tank before lvl 190
full tank makes it almost impossible to kill anything fast
my def of full tank = someone whos only role is to tank/they dont care about damage as long as they can last long and keep aggro
