Thanks again. I use a system with just one main Magic skill for actual spells, not individual spell-skills, but there are also other magic-related skills to spend practice/training time on (Ceremony, Sensitivity, Enchanting, Loremastery, Alchemy, etc). So hopefully it won't be a problem.

But I'm still worried that it might be: Would lots of combat-related Powers be too tempting for sorceror-type characters?

I wonder whether to invoke the "hours in the day" principle: there are only so many hours in the day to practice your magic/combat/sneaky/holy skills, to keep them up to scratch. Characters who want them top-notch should concentrate their "off hours practice" on one type, or they'd lose out...
