1) Solo roam orvr if logged on viable roaming class (solo roaming as heal specced healer is not that great experience imo)
2) Get that scenarioralert addon and tab out and do something else while waiting pops
crafting.. be it butchering or making pots. My mastery, renown and tactics selection is very different depending on if i want to play rvr or scenarios so if i decide to hope for scenario pops, then doing RVR while waiting doesn't really feel like a compelling option. only crafting or simply wait.
