You clearly don't know annie very well if you don't take a point in molten shield till level 13... you need a point early on so you can recharge your stun in a teamfight or gank. Why would a champ like annie who doesn't have the best scalings in the game and generally uses ignite at the end of a combo need an extra 10 ap from ignite rather than summoner spell cooldowns in utility.. There is also very little point in risking a soulstealer in anything but low level games. Annie has huge burst without it, and for a champion with no escapability other than flash, you really do not want to be drawing any more attention to yourself kill priority wise than absolutely necessary, and having a soulstealer is like painting a target on your face.

going 10/0/20 makes very little sense as well as putting 3 of the points in Good Hands. Leveling up E last also makes very little sense as you should have at least one rank of it before you're forced to max it out
