I had two questions. Firstly when you charge a unit you must do so in a way that means the maximum number of models fight on both sides. Unit blocks will therefore have to charge dead centre obviously. But with something like chariots can you choose to charge near the edge of a unit as long as you have the max number of models in base contact? I ask because it may be useful to keep my chariots within inspiring presence of they can be a couple of inches to the right or left of the centre of a unit.
Second question is if you have multiple casters (say 3 level 2s) do you swap for sig spells after all the wizards have been rolled for (thus increasing your chance of getting to choose from a double) or do you have to swap for sig spells when each wizard is rolled individually (decreasing your chance of getting to choose as you could roll the number you swapped out with the next wizard)?
