It's a limit, but it's not a good limit. That spell is all kinds of nuts, half wildly overpowered, half confusingly worthless.
Yeah, I think Shapechange may be one of the most confusingly worded spells there is. For example, say you have Body 3 and turn into a rat. Now, a rat's typical stats are going to be on the low side (1-3), but you get +1 to all stats per hit... does that let you go beyond the racial maximum? What IS the racial maximum for [animal]? Do you get proficiency in the skills a typical animal of that type has (fly, natural weapons)?
So the spell is confusing. But what I like is that it rewards you for having 2-3 Body, because otherwise you can't turn into really small animals, which are very good for infiltration purposes.
Multicasting does not cause any problems if you do not allow to add any kind of bonus "after" dividing the pool but apply stuff like visibility modifier and wound modifiers before... I think most of the trouble with multicasting is coused by some munchkin way of reading the rules...
The idea of multicasting may be salvageable (there is also multi-shooting with two guns, or melee-attacking everyone standing close together), but it really needs to be looked at very carefully to limit abuses. It might be simpler to scrap the option as being not completely necessary and difficult to repair.
I agree with this in general. My problem with Shadowrun over the years, and more so with 4th edition, are the "surprise!" moments that can happen with shitty rules. A lot of the problems with magic are things that pop up during play that we then have to hit with a nerf bat. SR4 was a big step away from balance between mages and mundanes.
Basically I'd like to hit a point with SR where there are no trap options in character creation and no accidental god-beings.

It's very unfortunate that making munchkinized mages is probably easier than making a halfway decent Sam. But avoiding traps in character creation and preventing powergaming is almost impossible in any point-buy system. With great freedom in CharGen comes great responsibility.
