I mostly play a dedicated thrower, and I kind of disagree with this, in general. A few items here and there could use a buff ammo-wise, but damage seems to be at a good point.
The main issue is the ranged stun nerf, really hurts dedicated throwing a bit since you can't keep a long distance like an archer and still expect to hit things reliably. You have to get in close, and if you can't stun someone, you might as well not even have throwing since you'll be forced into melee anyways.
That being said, I mostly stick to Stone throwing lately (I suck at accuracy and tend to TK way too much with jarids or lances). Usually just support people by staggering enemies in combat or stoning archers, but was able to get 3 kills in a single round this morning. Throwing does not need a buff if someone as terrible at it as me can occasionally get decent kills.
