General DiscussionWhy does valve not release new items?

Because Icefrog is in charge of that and last time I checked, he'd probably need a new vendor in warcraft 3 to cram new items in.

Boo dota 1 yay dota 2

Not like some things happen in dota 2 that don't in dota 1.

...not that I know what we're really missing at this point...

I think a miny sunder -> 350 hp swap would be cool on supports (like abbadon)
Maybe a new carry item where pure dmg is conveyed after every hit (like a poison)
Item where each hit gets + 1 main stat for a min

You seem to be willing to emulate some of the heroes skill (some items already do that).
Couple of those you've mentions are currently missing on items and could be fun to introduce them.
I'd also like to see some changes in the current items or maybe by getting an additional recipe an upgraded version of them.

Who knows, might as-well see some I'm the near future.

The only thing I want items wise is something else to build orb of venom and soul booster into. What they would build into I dunno, but it would be nice to have more choice.

some of the wraith night items were pretty amusing, loved the lvl 2 arcanes and green aracens :D

Something like nome's wisdom would be nice.

more viable version of harkons blade would be amaizing here s description of harkon for people that didnt play hon
Passive
+35 Intelligence
+27 Damage
+10 Attack Speed
+150% Mana Regeneration
Harkon's Blade Effect(s)
Attacks deal Magic Damage. Applies Harkon's Blade to the attack target for 3 seconds.

Description
While active, changes attack damage type to Magic at the cost of mana per attack. Attacks also reduce Magic Armor of the target temporarily. This item contains an Attack Modifier. Attack modifiers are exclusive and do not stack with other attack modifiers.

never licked harkons, broken item.

hard item to balance but i think it gives extra (depth) and 'alternative' way to play against heroes with very high physical armor and illusions
Good ol times when harkons wasnt attack modifier zO

something like spellblade from LoL would be nice (scaling from int gain mostly)

keep your hon and lol items in those games

lol why the hate? lol has many good items.

Nukers not scaling and being powerful early game instead is an integral part of Dota. Having AP items will just make carries build BKB even more, and it's already an overused (perhaps justified, though) item.

Id like an int version of Yasha and Sange which then can be merged with either of those. So that's technically 4 new items.
