I think a lot of players were fearful it might replace or have a detrimental effect on RQ. And the reaction was a natural defence to having their toys taken away.
I think Jeff’s comments have assuaged those fears, particularly noting the benefits in terms of queue times.
Personally I think the matter was so divisive that the two effectively have different audiences in any case, and that rivalry between the modes is likely to continue in some form or other for some time.
But that’s okay. It has brought players back in to the game, I’m living proof of that, so for me it’s a no brainer that it’s good for OW.
