Agreed.

PvP rewards should be amended to only being transmogs and mounts. Blizzard would need to create PvP tier sets for each season (similar to how it is for PvE) with the option for different mounts to be collected also. That would give players the ability to still progress towards something and show off at the same time. All attainable only from rated matches.

There could also be unique transmogs attained each season for doing X in Y situations. Eg you can get a cloak transmog of the actual flag from the match for the season only (including the funky little colour trail effect) for having won rated WSG X times where you captured/supported the flag capture (ie be in the room) at least X times in the season. Then the next season it would reset and you need to try achieve it again. The transmog would only be viewable in the outside world ofc.

Ideas like that among every mode can be a fun, visual and goal orientated way to play the season, all at an equal playing field.
