I am only comparing them to the passive.
As for 3 PRR perhaps giving you nothing, +2 spell pen doesn't give you anything if you dont cast spells, I don't think every past life needs to be beneficial to everyone. If you dont want more PRR then you're actually really well off - the divine destiny is the one most melee want but dont want to grind for.
And most people can use the PRR. You're right, some tank builds don't. Tank builds are completely unnecessary and a waste of a party slot outside off EE LOB, and I haven't seen an lfm for that in ages.
