Samurai as dps and not a tank, everything else looks right.
SAM shouldn't even be considered as a tank, imho. As the job plays more on the "mythos" (from movies, stories, ideals, etc) of the samurai rather than the historic accounts of one, we know they are supposed to be fast and agile. Same armor level as a LNC/DRG, high burst damage, and maybe a throwback to XI where thy build tp fast and have skills/combos hat could utilize a full tp bar.
Again, this is my $0.02 on an MMO video game forum. Please try not to take it so seriously. ^___^
