E: Not really, for a Critical strike is computed as a single attack thus armor resistance is computed once but on a double attack, amor resistance is computed twice, once for each attack.

^ Armor reduces a percentage of the damage dealt. 100 armor reduces by 50%, 200 by 66.7%, 300 by 75%.

If your basic attack deals 100 damage and someone has 100 armor it deals 50 damage. 2 attacks would deal 2x50=100 dmg and a crit would deal 200/2=100 dmg. 2 attacks=crit with the only difference that the double attacks can also crit making it 4x the damage in some cases. (crit and double hit do the same, but they stack, similary to tenacity and cc reduction)
