Hot take: If you tell people playing Winston to swap because he is being countered, there are only 2 valid scenarios for this unless you are top 500. Basically the whole team has swapped to spam damage like reaper, bastion, mauga, etc. In which case I would make the argument you can still play Winston into this as you are commanding so much attention, but that requires team play so in a solo queue I kind of get it. OR the other tank is a GOOD Junker Queen, with a strong emphasis on good. If you are calling for swaps in any other situation, you are the problem. I play into these “counters” all the damn time and win, often with my team still flaming me for not swapping… after we won, and I have strong stats, least deaths, etc.
The idea of how counters work in this game is about 9 years behind reality for most people.
