The problem is that every character shouldn't be viable for every situation. There should be times where defensive characters are the only viable characters to hold on a map. Just because something works well most of the time, it should have maps that are weak to use it on or counter picks. Pidgeon holing a game with this many diverse characters with drastically different play styles into one or two core meta builds is annoying as hell to me. I am glad pro players are using junkrat and mae and other characters that have negative views from the community. Inherently, any ranking system will have it's fall backs and I still hold to my thoughts that a good junkrat will have fairly low accuracy due to prefire and predicted fire. It's the only class that I feel like gets half of their viability from holding back enemies by angle shots and manipulation of projectile bounce. When playing junkrat I am firing almost constantly if I have any idea where an enemy or group push is coming from or going. Close range burst he is a monster as well.
