what would have been a better counter-pick?

Typical pub draft.. You had to win that game before 20 minutes, that was your only chance.. I'd have suggested a Pugna or Enigma or Enchantress or Chen. Even with Nature's Prophet, you could have pushed, pushed and pushed until you either won or lost. If you let the enemy farm, there was no way you were coming back since they pretty much had 5 cores.

Same, I'd suggest a Support...but there's no point playing Support if your Team doesn't know how to take advantage of a competent player.

I'd suggest a Jungler, but I wouldn't be surprised if Doom Bringer kept Feeding his Lane and crying because he was 1 vs 2

I'd suggest a strong Laner, but..no Lanes left.

He might have done, you rarely see Dust of Appearance or Sentry Wards in low-level Pubs and a Bounty Huner can easily make up for a lack of Farm in the first 5 minutes, with Ganks and [Track]] Gold in the next 10. Not to mention, Track Gold helps with the fact that you have too many Carries with not enough Farm.

I always pick Bounty when 3 or 4 people on my team make bad choices, at least I have fun even if my Team loses... ._.

You can try, but you'd need a little bit of Farm and at least 3 levels in Treants first. You can then push Top with the other 2 then rotate Mid, then Bot and create plenty of space that way. Fast, early Pushes depend on your teammates cooperating with you though. ._.

Prepare to be veeeeeeery lonely in Pubs! 8{3

Naga Siren also tends to make it impossible to farm anything for the rest of the team if the player uses her illusions to push with Radiance.

A solid hero in the beginning stages of your playing experience would be someone like Dragon Knight, great early-mid fighter, and has a monstrous snowball potential, and a great pusher with dragon form.
I wouldn't simply pick Slardar to counter invis heroes, he has a great skill set, and don't mitigate his ultimate to only the invis heroes, it reduces armor, by a bit. Great hero but in that situation you would've been better off with a high impact support.
Lion can pretty much 1 shot sniper at lvl6, has a ton of lockdown to make Anti Mage cry.
Alchemist play him as a support. At first, roam and kill, fast farmer, transitions quickly to a carry.
Shadow Shaman bunch of lockdown, great deal of pushing power.
Pugna literally blows **** up, manage your mana and blast buildings to rubble

Clinkz could've done well here, doesn't need much to come online and rain hell on people (for another solid carry not as farm dependent as a lot)
