Lord Warden is a decent group buff set, for stacked and stationary fights. It is most commonly used for progression teams to give Damage Dealers a little more resistance and survivability. This set also gives some self resistances which you might find useful if you are not a Nord Tank.
The most difficult part is the 2 pieces bonus group buff requires you to stand still and be stacked for it to be effectively used. It has a really good potential 100% uptime so it can be a reliable set to use in terms of uptime.
