Cool.... quite a few players who never touch/play a healing class character are often somewhat clueless about things from what I have seen. One reason I see so much self sufficiency in guilds is that I would guess a lot of long time guilded players have rosters of characters which include at least one healer among them (perhaps not player much, but at least enough to get a feel of the class).
As you have learned, topping off is an excellent way to waste SP, (which is why I was wondering about CSW wands being used). It can sometimes be amusing seeing how low you can sustain the party at and not lose anyone (especially amongst friends). (Quicken helps you to cut it even closer...).
