Souveran body has enmity+ on it. That's the main reason it's better. You can also get more -dt with 2 or more souveran pieces.
War isn't used in tanking either anymore. What makes pld better is it's abilities and (job spesific) gear.
Every job needs defense sets in case of tank losing hate or seeing high dmg aoe attack about to execute.
Don't blame me. Some guides are out of date because OPs stop updating them.
Tanking trash mobs? For content that don't need main tank? If you read the top you see "Samurais are considered one of the big three in the current end game in regards to DDs". You can't dd while tanking, excluding hybrid sets. You'd be wasting sam's dd potential.
