So how about extending the depth of the casting queue?

[Yossar]

I would much rather have a better casting AI than a longer queue. But I don't know if that will happen until Dom 3. Being able to tell a mage to just cast one or two spells would be really nice, though. But I very rarely need a queue of different spells to go beyond six or seven. Most SCs will run out of fatigue by then anyway.
