I disagree strongly.
Here's a game I played in ranked where me and Yas were basically 0/5 like 8 minutes in. Rest of my team wanted to FF so bad, but instead of agreeing we played it out and came back and won. I have a mentality of "might as we ll just play it out because 1 fight, 1 opportunity could win the entire game!". I do agree hostage holding is toxic AF, but there's a fine line between that and just playing it out because you want the W.

Sadly, the next game me and Cait were smashing and my team wanted to FF like 4 times throughout that match as well.
