I think avatars should act like sort of 'pet' (not to feed and stuff but by how you can operate it). What i mean is, while idling, it followers the summoner, who can choose to send it to attack by mouse click, like you would do when targetting with your wand. And since you cannot cast with an avatar summoned (as it will destroy the avatar) i suggest a different colored target, like a blue/purple one.

Anything targetted, the avatar will simply attack that object, or move toward it.

Also, avatars are pretty weak if you consider they are actually like a representative of your god, not saying they shud be hella strong instantly but wis level should play a big role in how strong your avatar is, so that they can actually be used in battle, like in wars.
