5000 resilience rating is roughly what is possible with full resil gems, including this seasons meta, chest enchant and the 2x trinket resil bonus (its a bit more actually, and with jc + bs you could take it even further).

5k resil rating = 71.2% resilience.
or a 17.7% dmg reduction when you go all out on resilience (with JC/BS around 18.5%).
