I'm trying to say, consider the motivation for why you were so upset at the change, and consider the players on the other team, how your games may affect them, and how they may feel about the matchup.I don't even understand what you're saying here. I duo with people because I think they're good.
You keep bringing up different things instead of commenting on what I post, so perhaps I'm failing at communicating. For instance, you mentioned Diamond V and Platinum II. When did I (or anyone) mention that combination? You can still play it, so that can't be what you were upset about.
To respond to this specific post, you duo with people because you think they're good. Ergo, you think they're...diamond/platinum level good? If so, they'll get there and be able to duo under Riot's new system. If you think they're...gold level good? Well, that's not a well-matched game and that's what Riot's new system is trying to avoid.
I'm saying I think it will work itself out, while avoiding some abuse cases, and that seems to be Riot's overall goal.
On a personal note, tonight is a huge milestone for me: I finally unlocked the last 4800 IP champion. Only 6300 IP champions left!
