I loved teambuilder! Blind pick was lame, always a toxic fest, and ranked meant pick order or get lucky with someone willing to trade. TB was the place to go for trying stuff out, with people who would understand *before* the game, what you intended to do. If any player was uncomfortable with the team comp trying to find a new team was easy and quick, opposed to a time out on matchmaking and potential LP loss for dodging. To this day I don’t understand why blink pick was kept while team builder was canned. The ranked queues got fixed eventually by bringing back solo/duo and allowing 5s to become flex. While position declaration helped a ton, it doesn’t allow the same freedom that team builder brought. For example an off meta support like Katarina fared better under TB than position declaration.
