Battle has some options including eventually getting weapon specialization, bane weapons and flat bonuses to hit and damage for some rounds per day.
Flame offers some options, too by giving increased mobility (speed increase, nimble moves) in addition to allowing to see through fog and smoke which can be useful when combined with spells generating smoke. And eventually all weapons the shaman wields get the flame property.
Mammoth gives the ability to daze opponents with your fists and eventually increases your strength. In addition it has an option to give an opponent penalties on CMD which he can then exploit by using a combat maneuver. And he can buff his AC by increasing his natural armor.
I'm not going through all the spirits now but there is potential in some of them.
A Heavens Flame build has some potential depending on spells.
For one color spray lets you stun initially and some creative application of Hexes and Hex Vulnerability means you can keep a target down.
A personal favorite of mine is Misfortune then HV for another few rounds if the target is still standing after that.
