Or just a matter of considering that everyone is moving, ducking, etc. Maybe evokers are just better at timing. Maybe line spells are not lazerbeam straight.I see it as simply arcing around the target.
I'm AFB right now, but I'm pretty sure you can't fireball yourself. I'm pretty sure Sculpt Spell only works on other creatures, not the caster. (I'm speaking in terms of RAW, obviously).
RAW says creatures that you can see. Unless you are blinded or otherwise heavily obscured from yourself (or somehow not a creature) then you are a creature that you can see and can sculpt spells around yourself.
