I was looking at what the future holds for my Wizard, and read the Spliced Weave entry that specifically states that if you use Spliced Weave, you can't use Concise Casting in the same round. So, obviously, thinking on the combo changed before publication of the Companion (the post I quoted was before the final book was released.)
I'm just wondering... why? Would two fully charged spells in a round really be that much of a problem? Especially considering the Strain involved? (Minimum 4 Strain per round, likely more. Even at 15th Circle Spellcasters aren't going to have huge Unconsciousness Ratings.)
