Grux isn't great if you can't snowball the lobby and the higher you climb the harder it is to win with Grux because he falls off so hard late game. Might wanna work on expanding your hero pool. Your builds are also a little suspect at times. When you laned against Feng, you went pure damage and didn't really build any health or defense. What wins games in standard won't help you climb in ranked. I'm currently about to hit gold and these are the things I've seen as I've climbed.
Its hard to expand my pool sometimes when playing on 200 Ping. I went into ranked with the knowledge I have in standard, and your right. it doesnt work. But Its hard to play casters, ADCs, and even most supports cause I cant hit shots with 200 Ping. then offlaners, i really should get more heroes, like Sev, or Feng Mao under my belt.
