how are your butts getting handed to you? there's probably a larger problem that a simple trinket swap won't fix. I'm not saying the little things don't count, but it's almost always better to find a cure rather than just slapping on band aids.
keep abolish poison up on the priest so he doesn't get snared, cyclone/root the rogue when necessary, keep him slowed, fear if need be, help the priest with timely intercepts/intervene+disarms etc. depending on the gear level of your priest he should be able to survive for quite some time. depending on the make up of the other team, that rogue can be your primary target as well, just make sure u get behind him.
