Can ranked queue be more even?

I think ranked game is very hard to climb because the queue system and the LP calculation has lots of improvement. For example. I can be on a game with one Gold 5 four Silver 2 but enemy team had three Gold 5 two Silver 2. And I lost 22 LP because of that. That is very unfair because I lose more LP because I was in a higher ranked at my team and I cant carry them. In contrast, I gain less LP when I win a game at I am higher rank. Moreover, the dynamic queue should be improved by putting similar ranked player at the same position. For example, I had an enemy Gold 5 top against a unranked top. At the end our top had 38 cs at 17 mins and 4 death. If Riot put the ranked like that, it was totally winable.
