Just to chime in, you are free to criticize the game, as long as it isn't too ranty because you've lost a few matches or something like that, as we get tons of those and it would leave a bad taste in the subreddit's quality if rants were the majority of posts.
As for the bug report, the main problem is that it's inefficient. Titan employees that are on customer support rarely visit this sub, so this way they'd miss a lot of posts, and people would be posting here instead of somewhere where they'll actually get more help. Even this situation that occurred now is a huge exception to the rule, as I personally can't remember the last time someone's account/game issues were solved by titan employees on reddit. It just isn't that efficient for users.
