Max E > R > Q > W note: most guides will say max R first. It is impossible to put a point in R that would block points in your first-to-max skill. Pet peeve.
Your goal is basically to keep your lane/team topped off on health and to provide good engages. Your damage greatly stems from sunfire, your passive, and of course ardent censor. Your exhaust will be up very frequently, plus you have spooky ghosts and an AOE shield for additional team defense. When the going gets really tough, pop your ult. As long as you camp your adc, keep'em buffed, and peel enemies like they're oranges, you should come out ahead.
The nerf to E does hurt this build somewhat, but it still works quite well.
