Which the playercard gives a tangible metric to measure.
No it doesn't because you get knowledge of the stats from
looking them up, knowledge of the meta from streamers and other pro's, and logic is pretty self explanatory.
None of these things have any relation to player card, at all.
Yes, it does. If your player card was completely empty as you didn't play the game the quality of your argument would be zero. We don't need 'theory' players chiming in about balance, we need real players who represent all of the game modes.
If a person took the time to watch streamers, look up stats, watch replays of tournaments, and make themselves knowledgeable about the meta than chances are more than likely that they play the game a fair amount.
It doesn't take any of the things to make a logical balance argument to be good at this game, all you need is good micro and a basic understanding of the unit counter system.
Someone who has reached atleast top 100 in 1v1 ladder has a much better understanding of the game than some guy with rank 2000 and think he knows the game by theorycrafting and watching streams.
How does getting to top 100 make you aware of unit stats or meta knowledge? It means you have experience, but what it takes to be good in this game isn't in any way related to the ability to construct a logical argument.
Quentin is one of the best players in this game, and he is utterly utterly bonkers. Do you think he should be an authority on balance?
Sure thing, rocket scientist with bunch of diplomas in physics and random guy from the street have equally meaningful opinion on quantum mechanics.
The difference between a rocket scientist and a average person is multiple years in college and thousands of hours of studying. The difference between players of different skill is good micro.
Playercards are not really important, unless someone talks some extremely biased shit while swearing to god to play all factions, in that case by viewing the playercard you can instantly identify fanboy warriors of one faction only(like out friend alex here).
I'm much more willing to take discussion with inexperienced player seeking help then one army megalomaniac hero seeking supremacy, playercard lets you easily tell them apart.
Also as a general rule, the better the player, the more valid the opinion simply because good players understand the game and units much better then 5 digit rank ones.
You have made exactly 5 posts in the past 2 weeks that don't involve a personal attack on me lmao.
