Fan of Knives - Cooldown is too long for it to be worthwhile. Even if you hit enemies with it you are too close to get out of range of their melee attacks and will probably die.Caltrops - Been stated, enemies are unkiteable in hell+ Entangling Shot - weak damage, takes too long to slow second target, basically worthless v. mobs of enemies.Grenades - Too short range / unreliable....
Thank you (as well as a few other recent posters) for a legit response to the thread that helps build it up. I do disagree on a couple points though:
Multishot is great with Fire at Will, but the Discipline gain has a place too, if you want to focus on safety over damage output.
Second, Entangling Shot is actually not bad. It (alongside Grenades) generates 6 hatred per attack (with one of its runes) instead of 3, making it my prefered primary going through Hell, since you waste less precious SS time generating Hatred. Also, when using Cull the Weak passive, it pretty much guarantees 15% bonus damage with every shot.
I don't get why people are so adamant about nerfing abilities, it's not like you are getting an advantage over anyone else and there currently isn't any PvP that they need to be balanced around. I agree that some abilities are useless and need a buff, but there is no point in nerfing abilities, especially defensive ones.
It helps legitimize what you're suggesting. If we only asked for buffs, we'd just look like we want to be supercharged or suck at the game (which too many people just assume over the internet anyway).
In the case of SS, it's also about the skill not being used as intended. I have no problem with it being a central defensive ability, but its clearly designed to help you kite or escape (or revive), not stand in the middle of an army and tank. Demon Hunters aren't designed to do that, but the misuse of this ability is making it the most popular DH strategy.
Let me reiterate, I'm not suggesting making SS crappy, or taking away the only way of playing a DH in inferno, I'm just saying it would be great if Blizzard could return it to its original purpose while still giving us Inferno options.
