Question for DotA2 players...

1) Nope, tradeable from the start
2) Yup
3) Nope, you must play

Also, the more you play the higher your level becomes and the better drops you qualify for. :)

1) yes
2) yes
3) yes but im not telling you :P

To answer your questions:
1.You don't need to purchase anything to trade, there is no becoming a premium player thing
2.No you cannot acquire items from bot matches unless they are co-op matches or online games
3.No you cannot idle, you get drops after every game, which can last up to 30 min at the least, although you are not guaranteed one.
Just play the game for the fun of it, because grinding for items is time consuming.

1) Nope, tradeable from the start.
2) Yes you can aquire xp and items from co op bot matches which are easier than real matchmaking with players.
3) idk if there is any way, I didn't even try to search for it becasue I love to play that game.

1) Nope
2) Nope
3) Nope

You get items for leveling up.. (not in the matches.. your profile level).. otherwise I only got treasure chests.. May not be the same now.. I stopped playing few months back.

You want to play dota just for drops? Dont, just dont. You and your kind please stay on tf2 and dont ruin the game.

1. I dunno about this. I've already purchased something though.
2. Yes.
3. No.

Btw, getting good items isn't easy. Some people have played more than 1000 matches and have never got an item above Rare (or even Uncommon) rarity. Besides, if you wanna play, you should do it for the long haul, not just for a short time in the hope you get items.

If you idle, you're mostly likely gonna go into the low priority pool and get a lot of assholes swearing at you!

People like you are why I quit TF2 all together. PLEASE don't bring this kind of garbage to DotA.

1-No, item drops for everyone.

2-Yes but obviously you need to be online.

3-No, don't even think about it.

And my advice, don't play DotA for items.You'll be hated,reported and probably banned if you join online games without any knowledge of the game.Just make all the trainings,play on "noob" modes and stay away from ranked games until you actually know all the game mechanics.

1) No

2) Yes

3)There are ways to do that, but keep in mind that you are going to ruin other people's games if you idle.

Item Drop System - DotA2
The item drop system is a feature that allows players to obtain in-game cosmetic items through naturally playing the game and with no purchase necessary. This system was inspired by the drop system from Team Fortress 2, but does not function entirely in the same way.

mainstream on now,don't wish to play it anymore..
