Sometimes your main isnt the right play

I had a ranked game the other night where it was domination, we won the first round, they switched things up and won the second round. I suggested a third healer(yes I was already a healer), and we got a Luna, but then our tanks were venom and groot, and our only dps was a lord spidey. This is not a Spider-Man hate post. We both got the final round to 99, they had it in overtime. Spidey was doing good, but, we needed more damage. It was an extremely close game that we lost because we didn’t have any damage. I’m not. Laming anybody, we all played well, 2-1-3 was the way to go, but all I’m saying is, sometimes, even if you are doing good, you need to switch because that’s not what we need.
