My 2 cents on this topic and excuse making in general.
It's very similar to when you win with a top tier character; that makes you a tier whore, or when you win with a mid-low tier character, and they didn't know the match up. Universal excuses that are super petty.
Counterpicking, tierwhore, lack of mu knowledge, etc, are all excuses that can be said nicely, and at the same time imply that you didn't actually lose because of being outplayed. The character loyalist is like the ultimate one, because being one covers you for any loss, automatically, in a lot of people's eyes. If you exploit that by counterpicking, you're effectively attacking all of the excuse makers around the Mortal Kombat world.
At the end of the day there are no valid excuses for a working game that gets patched frequently. It's not like they put Tanya in the game and couldn't nerf her. NRS could be changing things and they aren't, so everything is meant to be in the game as of now. If you lose to Quan Chi, you can pick Quan Chi, or a different character that can fight him better. Unless you play Mortal Kombat X online where the game isn't always working, you have no right to complain about anything. If you don't like how they made the game, go play something else.
Edit: I'm not hating on people who make constructive posts about the game and characters. Just the people who will come out and say/imply ridiculous stuff when they, or someone they like, loses.
