With the current gear available to us i'm inclined to think the same thing. Haven't had a chace though to play with Ariyala to have a look yet though (stupid work site blockers :'() You've calculated the stats correctly (my maths has come up the same) but your missing weapon damage as i'm pretty sure the i210 has 1 more WD then the i205 which is an extra 10.625 str right there.

However unless we can up the crit on our gear without sacrificing acc (unless you've been bloody luck with diadem drops) then mathmatically the relic is better, until i'm able to play on Ariyala (most likely sonmeone on the forum will do it before me) i don't think we can have a gear setup, (out of ESO/Savage drops) that could validate using it.
