Provided they're ineffective against dragons I'm fine with that.

Throwing weapons or posions? I imagine a dart wouldn't hurt a dragon at all, but a throwing axe might hurt it some.

Snowballs! Why does everyone always forget snowballs?

Great for a distraction, popped in the head it's a stunning blow, not to mention a taunt, or even stacking snowballs for a consumable snow fort for the end big end game battle!!!! (adn then the dragon breathed fire.....)

...and their reasoning is: it won't add anything to the gameplay...and they would know since they are playing it everyday.

thats as reasonable as getting rid of every melee weapon but swords because axes and warhammers don't add anything to gameplay that swords already do. no its simply moronic to limit ranged combat to one weapon and to say that no gameplay is lost. just because you didn't use them doesn't mean no one else did.

Return of throwing weapons will great,

They are not crossbows so will not looks outside of technology level in Skyrim (there is still can be an dwemeric artifact crossbow as prototype for http://www.tesnexus.com/downloads/images/22684-2-1237587327.jpg),

Throwing weapons isn't hard to be done,

Throwing weapons will expand Marksman and make it more interesting and variable,

Work well with stealth alchemy as throwing flasks of Flammable Oils, Damage Equipment Acid, Slippery Grease, Poison and Paralyze Gas, Smoke or Flashbang Bombs etc.

Add ability distract enemies guards with with throwing clutter around

Some throwing weapons can relay on Agility and Marksman so poison needles and darts, stars and daggers, can be usable by nimble characters, some on Strength and Marksman so powerful characters will not relay only on melee combat but also will have some options for short and middle distance like Throwing Axes, Javelins, Throwing Hammers, Stones for Giants

Throwing weapon isn't has the same purpose as bows have bows work middle-long distance need better targeting and usable for sniper and need time to be drawn, bows utilize both hands for work like two handed weapons
while Throwing weapon work on short-middle distance not need better targeting so there is no bow sway effect, usable for silent kills at short distance, take smaller time to draw, utilize dual wielding (we can throw two projective at one time) and even with some skills (perks) can give ability throw more weapons at one time thats anologue of dual wielding for marksman weapons.

No need different or special button for Throwing Grab Key can be used with Strike Button for current hand Simulationsly, hold it for some time and release will allow throw current equipped item forward, holding it more will allow thrown it furtherer, use just strike button will swing weapons as melee weapon, if throwing an clutter no need to show it in equipped in hand and quick tap of grab will drop item, while another quick tap will allow garb item again, no need hold button for dragging item around.
