How unbalanced are my rules for scrolls?

[thom99]

Nerfing wands is effectively a big nerf to warlocks and spellthieves, for example.

Well, my homebrew doesn't have those classes (as PCs anyway) , but that's good to know.

Wands and scrolls don’t generally feature in high output T1 cheese...Martials with wand chambers benefit proportionally more than T1.

Hmmm, also good to know that, thanks. I haven't run 3.5 in a while so I missed that aspect of T1 vs T3. My primary concern is not letting any wizard or cleric become able to do everything better than anyone else. I've researched the various "broken spells" threads on GITP and closed down most of those loopholes. I'm concerned about swift spells in general, not any spell specifically.

What I'm getting so far is that my concerns are (probably) overblown, which is what I wanted to know...
