I'm actually so surprised how hard Silver-Gold elo really is as a former 1-trick Diamond Ryze.
I've been messing around on one of my accounts... granted, every game that I play Ryze on it I'm completely stomping kids with around a 21 KDA (not this account). However, when I play anything else, especially something to enable my team like Galio/Twisted Fate etc... The games are so fucking hard. The main problem with playing Galio is that (especially when you play full AP Galio like I do) you have to depend on your teammates to actually run behind the enemy for your ultimate/engage, and they never do. No matter how much you tell them, they won't. The people don't lane bad, it's just the decision making. It's actually so bad.
Every single game, you better hope and pray you have a smurf jungler, cause chances are your jungler is complete garbage and the enemy jungler is going to gank whoever has a high KDA over and over and over in order to destroy the one threat on the enemy team. It's not random either, I mean CONSISTENTLY shit junglers and I have been unlucky to have the worse jungler on my team 4/5 games in a 20 game sample. If I really wanted to I could just spam Ryze, but the state of the game is so bad right now with the addition of stopwatch, which is made worse by Riot's refusal to ever admit they make a mistake and remove it, I have zero desire to really put in any effort besides trying out different champions.
I feel really bad for people who are experiencing this.
