Does Bloodstorm blade have any flaws?

[CyberThread]

Being able to throw a mountain around, and hit everyone and have it return to you, is a great skill, but what flaws or weakness does it have compared to a usual thrower build?

[Vaz]

It's not a Full Caster?

3 levels are also a fairly big investment, and make a melee character a thrower, but it doesn't really make a Throwing character any better (or worse) than what they're already capable of doing/being.

[Grod_The_Giant]

It doesn't advance maneuvers, either, of which you need a few to qualify. So that's something.

(Also, the "throwing a mountain" thing is Hulking Hurler)

[Amphetryon]

What are you calling "a usual thrower build," CyberDrag? I presume it references some specific combination of PrCs, but both Master Thrower and Hammer of Moradin - the pre-ToB usual suspects in thrower build discussions - are both rendered fairly niche in most discussions I've seen since ToB came out.

What's the baseline you're using for comparison?

[StreamOfTheSky]

It doesn't advance maneuvers.

Which means at higher levels, it's actually inferior at throwing things than a straight classed Warblade, because Lightning Throw >> anything Bloodstorm Blade can do. Among all the other things you miss out on from loss of maneuver/stance progression.
