A Pub Game- Why You Should Save Captains Mode for Games in Parties

So, hello again, .Elusive here. Today I'm going to be taking about an unranked pub I played today with a good mate of mine, and what went wrong. This is by no means a high tier game, but I will try analyzing it and showing my/others mistakes.

First off, they immediately banned Doom, which (we thought) signified lots of big ults. Our captain banned Pudge as a personal ban, then banned Sniper after they banned Phantom Assassin. He then picked Lich on my mates request, then they grabbed Witch Doctor. I realized they were probably going for big team fight spells to set up for a tunnel vision carry such as Sven or Troll Warlord. They picked troll second before we could ban, and so our captain banned some solid supports. We then grabbed Meepo? I think the captain thought he could counter troll.... Then they picked Lina and Enigma and he decided to pick Windranger for mid. On behalf of the Shadow Shaman player, the captain banned Storm Spirit because he was "broken". We picked up Sven as a tank, and they grabbed Wraith King.
Now, everyone got their heros. Me and mate mate were going to lane together, he as Lich and I as Terrorblade, but the captain picked lick and made my mate play Sven, who he has no experience on. I had to play Meepo. Our lanes went like this- can you guys see what was wrong?

Hard lane- ss and Sven
Mid-windranger
Safe lane- meepo and lich

They laned:

Hard lane-wk and wd
Mid-lina
Safe lane-troll and enigma

If lich had gone top, like was asked, he could have kept the wave pulled back to our tower, which would have given my mate free farm and kept troll and Enigma from getting easy xp and farm. If shadow shaman had gone bot and leveled hex or shackle, I could have gotten easy poofs off and been fed. As it was, Lich pulled lane AND Denied creeps with his spell, so we lost our tower early since The creep wave was always pushed up. I wasn't able to get farm, troll got fed, and we lost in 30 minutes because they took both towers in the safe lane, which meant I couldn't get farm in jungle safely.Our Windranger also did not rotate, and Lich used his ult in 1 teamfight. I was too ballsy and got a Meepo chainstunned and gave away several kills. It was a terrible game. Ah well, you can't win 'em all I guess...

Any tips on this? It was a terrible game, and Id like to try and improve on it.
