Not enjoying this preseason much at all (remove thunderlords and lower death timers pls) but the new champ select might keep me playing ranked. I've been diamond since season 3 but I honestly wasn't going to bother this season with how the game plays out now. But since they're bringing out pure soloq (dynamic queue is not something I'd ever take seriously) I might give it a go. I imagine it'll be harder to get diamond this season since they're gutting my playstyle but we'll see.
The deathtimers are necessary to prevent 50+ minute games. I've been on the bad end of them myself but they are a good thing.
