If you're trying to take advantage of heavy weapons as a warrior and you don't take Trapping, you're gonna have a bad time.
Fist/balance would do so little for you I understand how you con died.
When you're planning the build, have some ideas of what you're going to be wielding and against who.
If you wanna wield two shockwave axes like a boss, fist/trapping isn't a bad idea as a storm giant. Second spec could be polearms since there isn't a shortage of heavy polearms in the game (especially ones for you to request)
If you're planning on using swords, all the best goodie swords are super light. Trapping isn't going to get you much distance, but warriors have ONE rule and you should follow it with any build.
The golden rule is this: Damage is king.
Next time, try a storm giant chilling/cry of thunder, sword/fist and I guarantee you will be melting peoples faces off quicker than they can say, "I need the special tin for Dorothy"
