Complaining aside, I think this is a great idea.
Not sure if any of you here play that Iron Maiden: Legacy of the Beast mobile game, but they recently rolled out a new PVP/arena system. While it has its flaws, one aspect of it I really like is the fact that
1. On the stats page it shows your offense win/loss ratio
2. It also shows your defense win/loss ratio
3. When you get further into the data, it also tells you who beat you (and who didn't) and allows you to fight back, which is extremely useful because it gives you a chance to test your setup against whomever beat you. You can't swap out toons yet, but it's still good be able to fight back and see if it was an issue of RNG, bad AI or just the fact your team really isn't built well
Not saying that game is the perfect setup, I still think SWGOH is more fun in many respects but I do like the aspect of being able to ID who beat you, your real win/loss percentage and give you the opportunity to hit back to reclaim position or simply to test your setup
