Interesting reading this thread seeing peoples views on cleric/fvs and healing. I atm play a healer/caster fvs and a more fighty fvs (slightly gimped heh) and a fighty bard with some healing, although i have played all the classes to a high level.
Anyway I kind of agree with OP when I play my healer fvs I don't mind healing ppl i have quite alot of sp's usually enuff for me to heal the group and chuck the odd bb/cometfall. If I look like I'm not gunna make the next shrine without using scrolls then hell i carry 300 odd I dont mind using them. I also carry wands to remove curse blindness and disease which i hardly ever have to replenish they are cheap compared to potions although usually by the time i have switched to them the person has already drunk a potion.
I guess if I end up using lots of scrolls all the time it would get to be expensive but i find it rarely happens and on the odd occasion it does then i don't mind. Usually if i've been in a group which has only just completed a quest for whatever reason people will mail me sp pots and scrolls which is nice.
The only gripe i've had sometimes is the barb who always using death frenzy all the time in certain quests where i think it becomes a real drain on sp. Then i usually true ress him a couple of times. Actually thats the only time i've found getting slightly annoyed, i think if i was gunna do that i'd give the healer some scrolls and say well i'm gunna need all of these cast on me :P
