"Ruining other people's lives" is a little dramatic, especially when you have the option to play in ranked, where people are more incentivized to stick together, and there is a penalty for quitting.
But we're talking about unranked here, so let me tell you why I will NEVER jump with my jump master. Because he's an idiot. Every. Single. Match. Always a different guy, but always the exact same inconsiderate and idiotic behavior. They NEVER ping where they want to go before the jump, only after, and probably only then because they've realized that one of their teammates jumped solo. Inf**kingconsiderate. And then, to cap it all off, they ALWAYS drop in streamer building, or whatever is the equivalent on the map in question. That's the idiotic part. I'm tired of the endless stream of testosterone-soaked teenagers who know nothing about the game, but they have a favorite streamer and he always drops hot and wipes three squads in 30 seconds and they want to do the same thing. Not on my time, buddy. Not on my time. I'm not here to wipe your butt every time you go in a little too hot or bite off a little more than you can chew. Which is pretty much always. To put it another way, I'm showing my jump master about the same amount or respect he's showing me. If he doesn't value his own life why would I think he has any value for mine?
And I don't no-fill because I keep thinking to myself that there has to be somebody in this game besides me who isn't crippled by delusions of grandeur. As a solo queue player I don't kid myself with thoughts such as, "I deserve better teammates," but I'm certainly willing to keep looking for them. And I'll never find them with no-fill.
