Wildcard needs separate stats.

How does someone else having a badge affect you in any way, unless you're breaking the game's ToS by account farming and worried your badges you cheated to get fetch less money. If you're just playing the game, someone else having a meaningless badge doesn't affect you.

You know what does affect everyone playing the game that the devs refuse to address? There's a whole grocery list: laggy servers, aim hacks, recoil hacks, movement hacks, wall hacks, Chronus Zen and similar cheat devices, ping spikes due to the devs' refusal to prioritize stable gameplay over short queue times, lack of regional locks which also lead to unplayable high ping matches, etc. etc.... Basically the devs refuse to grapple with the reality that shorter queue times uber allies will not solve their player retention problem.
