Shaman legendary not so legendary.
He needs a buff for sure. Make him a 4/6 and make him cost 7 with overload 3. That would make him a relevant drop that can pick out drops, survive, taunt, etc... and land on a relevant turn.
If making him more than a "Argent Commander with Windfury" is a worry, then maybe balance him to have Spellpower? You could give him all major key texts but split them up into two forms that you choose between when played. Yeah Cenarius is another legendary that chooses between two effects but it shouldn't be that big of a deal. They would still be rather different. Cenarius buffs the field around him while Al'Akir is a card that only looks after itself.
Form 1) Windfury, Charge, Divine Shield (Overload 1)
Form 2) Divine Shield, Taunt, Spell Damage +x, +y Attack/+y Health. (Overload z)
I have tried it out in a lot of decks, but only seen it do any good on very few occasions. Sure its great if you drop a rockbiter on it and have it deal 12 dmg to the opposing hero, but its still 9 mana and 2 cards to do it.
