Your in game /bug report really is inadequate and more categories won't fix that. What you should do is provide a better, more detailed reporting tool outside of game.Thanks so much for the information and insight, everyone. This was really helpful. Just wanted to let you know that we will update the /bug categories so they're more helpful/accurate when submitting a bug report.
For bugs (actual bugs, not game design feedback), I use /bug because in my experience that's normally preferred by QA and therefore that's what I'm used to.
For all the good it does here. Either the bugs go into a black hole or else the developers can't be bothered to "fix the shrub that's hovering above the ground at head level"... for 4 years. So I just stopped bugging things a while back.
Thanks for the comments so far, appreciate the insight.
