For your combo perhaps it seems that way because you might not be able to pull off a quick nuke without using PvE gear. I've never played double dps but I would imagine you would still want at least 400 resil (I play with 882 and my partner 885). To me resil is there to let me live through a stun. I play druid/warrior - without resilience going up against a double dps team I would lose. Resilience gives me time to thing and react - it honestly makes arena more fun. Without resilience the match is over in 10 seconds flat. With resilience I've had many many very exciting 10 minute matches.
