The Anima grind is not the problem.

Secondary stats are not very strong in HW and much weaker then they were in ARR. If you do not have a 210 weapon the relic will be better then everything lower due to weapon damage and main stat being king. Having different secondary stats if a very very minor increase or loss.

This is just parroting phrases you've heard elsewhere.
The secondary stats are worth slightly less now than they did at level 50, however they still have significant weight, especially when there are in excess of a hundred of them.
The Thordan weapon is mathematically better than the i210 relic, and due to the huge difference in skill speed makes even more desireable outside of its damage weight.
