TLDR version:
Basically resilience currently double penailizes some talents because it is applied before the talents. For example, a 33/0/28 mage shoots a 1000 hit frostbolt that would normally crits for 2250 will instead crit on a target with 5% resilience for only 1875(16.67%redux) instead of the expected 2025damage(10%redux). Notice that this only effects the talents that scale off bonus damage such as ice shards and spell power and does not change ignite, which scales the entire crit.

This results in resilience scaling differently against different classes
Spell power/Ice mage=1.667R
Ice mage = 1.5R
Elemental shaman=1.5R
Destruction lock =1.5R
Balance druid=1.5R
Spell power/Fire mage=1.2857R(after ignite)
Arcane mage=1.2857R
Marks hunter=1.1304R
Rogues=1.1304R(only on abilities effected by lethality)
Arms warrior=1.0909R(only on specials, not considering deep wounds)
Feral druid=1.0476R
Fire mage=1RX(after ignite)
Everything else that doesnt have a crit talent will scale at 1R
