Q:
Could anyone point me to a shout build?
It can do pretty much anything you desire. If you want the highest power, a simple 30/25/0/0/15 with Berserker will settle pretty much all arguments about that. It’s not that survivable though, so it makes sense to weave in some survivability. Personally I ran 0/25/15/30/0 with Berserker/Knight while I was learning, it could shout heal and have a ton of passive healing with reasonable damage. Having a Warhorn is pretty much a must if you want to do group player-versus-player; trait it to convert boons, and a Hammer to bash people. A Mace/Shield is great for stun locking, too.
All in all I recommend learning about weapons for dungeons first; Axe/Mace + GS with full berserker and a defensive trait line allows you to survive reasonable well while you get experience and start to weave in/out whatever you prefer.
It is really difficult to make a Warrior build that truly sucks.
