In many ways, it's a worst of all worlds Super. Consider:
Nova Bomb and Shadowshot have greater range.
Arc Blade and Stormtrance have multiple applications.
Hammer of Sol and Golden Gun have both range and multiple applications. Radiance as well, and it comes with self-rez.
Ward of Dawn is purely defensive.
Fist of Havoc is one-and-done, and requires you to be at close range, both severe liabilities. Its chief asset is its near-infallibility. You let it go, and pretty much everything near you dies. And yes, it is the perfect Super for noobs. Indeed, Striker is the perfect class for noobs: tough, reliable, and simple to use. If a new Destiny player asked me what class to main, I'd say Titan without a second thought.
