4 successful hounds runs with pugs without any failures is pretty impressive... just wondering, you didn't run out of sp while on hound duty?
VoD can go smoothly without any (if much) resources. Had this happen like twice. Total scrolls burned between all the clerics 4-5, bard used 15 heal scrolls total, no mana pots, raid finished with half our mana bar left. Won't ever happen on elite but even VoD can be non-resource intensive. Most fun I've had in a while and the dps was awe-inspiring.
You'll find yourself getting much richer if you're more selective as to which groups you cleric for. Avoid people that make comments like "you're a cleric do your job and heal me" or those that send you tells asking if you will join their group because the only person they need is a cleric. Groups that are fine without one and don't go stupid the moment one joins the group are the ones that will net you plat in the long run.
