So the 750 rating for Seraphim gives you ~8% Haste. It will still always give 8% haste regardless of gear level too.
This obviously applies to all the other stats too except bonus armour cause armour has diminishing returns, but BA is still BiS
750 Mastery rating is still like 6% Mastery etc
Holy Shield always gives 15% block, but I believe that 15% block is worth more, the more block chance you already have as there is no dimishing returns, so I guess this has a tiny bit of scaling but its not because Serpahim gives flat rating and the other two give a % number xD Its just displayed differently
