That's a good point...err, 12345. I forget what your name is, heh! Anyway, that was exactly Splork's point. Cleric makes a great support class. On the other hand, send Bell into that area alone and see how she does against a 20 mil mob. Or, since that was 2 man you could see how she does against a 10 mil mob. If she's a 40 prime cleric, you might as well see how she does against a 1 mil mob. The results will likely be the same.
Noone denies that cleric is a great support class, either in part of a classo or as part of a group.
I don't really like the idea of using heal spells to damage evil/undead/negative energy creatures. Typically, people will just assign the normal points that would be healed as damage to the creature. That would mean a heal spell inflicts 100 points of damage, but it's 42 mana. That's an expensive blast for not so much damage. Later, even with 350 hp restores you're spending enough mana for 2 and a half winds on that restore.
It would be interesting to have more supps that are useful during groups. We all know (and love!) the chan chu, but some other group supp options would be a welcome addition.
Weasel, cleric primes do get a certain bonus to heals. The 3 spells heal, gheal, restore all cost a few points less mana. Restore costs 59 mana instead of 62. I don't remember for sure, but heal is a point or two cheaper. The bonus to raising is some amount of xp for the cleric if a cleric-prime raises someone. I think the theory was that its a fraction of the xp carried by the character being raised. I don't know what to say, it's a nice touch. It's not a whole lot of xps, but it would add up over time. During a quest like last night's, it probably added up rather quickly
Regarding using evil supps, I agree that they are more useful during a fight. Again, the real problem with supps is the alignment system. Clerics get a bonus for fighting certain types of mobs...dark dreams can be nice if you hit hard and carry a big stick...err mace, which procs nicely against evil mobs. Also, you can dispel evil and turn undead there, if you don't have a high str or a bunch of attacks. If you cycle there, though, or if you fight vs any evil mobs then you can't use the evil supps - at least not for long. It's odd that an evil character that goes on a killing spree might become angelic for causing that bloodbath. The two useful abilities that an actual clerics gets (dark mace / evil supps) work against each other.
