Precisely. If a player expects to be able to have as many scrolls as his character can produce, because of the rules of the game, then it can seem adversarial for the DM to "target" the scrolls. That is, why does the wizard have to worry about his equipment while the other character don't?
But if the DM is up-front about it, then there's no worries.
Edit: I was under the impression the discussion of this has gone:
A: Wizards are very powerful because they have spells for everything.
B: But they only have limited spell slots, so they can't be prepared for everything at once.
A: But they can make scrolls very cheaply to have access to all their spells.
B: But scrolls can be damaged and destroyed, so that's not a problem.
A: But scrolls can be protected from damage in a trivial manner.
Is that not right?
I'd tend to agree.....except that the suggestions of manners of protecting scrolls etc. that have been suggested have been sometimes far fetched (in terms of medieval technology levels). Yes, I know fireballs are also far fetched. But one just has to decide what level of technology is acceptable.
People forget sometimes that things that seem simple to us now, like screw top lids and zippers may have seemed like magic 600 years ago.
So, some of the means of protecting scrolls might not work.
It's not like as DM you have to deliberately go after the party's items. I'm just open with my players that I enforce those saving throws.
Does it mean that every adventure the wizard is losing all his scrolls? No. Absolutely not. Does it mean that over an adventurer's career, as he loses saves vs. fireballs and lightning bolts and such, that he's going to suffer item attrition? Yes.
Robes, scrolls, books, and wooden staves are all highly flammable. And not nearly as robust as adamantine items.
It's surprising how often people forget about those rules in game. I find it makes a difference when you track that stuff every session.
Same thing with carrying stuff......when you start enforcing encumbrance, people stop carrying a sword for every occasion.
That's all I'm saying.
In my campaign, my players typically didn't have a lot of item creation feats. It just wasn't an aspect of the game they were interested in. Now, every wizard gets Scribe Scroll. But aside from that, most of their feats were metamagic casting feats, not item creation. And even when they had Scribe Scroll, they rarely used it.
