Resistance in CO works on more basic cryptic math, in that the damage you take is divided by the % of resistance you have added to one.
So 16% resistance means 1+.16 = 1.16, the damage would be divided by 1.16 and the result would be the damage you take.
So 30k / 1.16 = 25862 damage taken still.
If you dodged the attack first, then avoidance kicks in like flat % reduction, each % avoided is the % not taken, so say you had 40% avoidance, and dodged that 30k hit before resistance...
30 * .6 = 18000, which, if divided by 1.16 would equal 15517 damage taken.
