That would make sense if it was a big thread focused around a specific issue. For example, you can tell that GNB players are extremely concerned about sound. You can then look at individual upvotes counts to see what sort of beatboxing they want to hear. Creating a big thread saying 'DARK KNIGHTS ARE ANGRY' might be vaguely helpful, but it's hard enough as a forum user to filter out the signal from the noise.

To be honest, though, outside of upvotes and reactions, I'm not sure how much of this feedback is actually being looked at. The party line in most of these interviews has been 'we play this game ourselves, we're just like one of you (except our dev team doesn't necessarily play every job)', and 'we love to communicate with players unlike the [insert lead competitor MMO's] devs (except that it's one way communication only). They clearly have their own vision on how this game ought to be played and the playerbase is wrong. The only difference between SE and Western dev teams is that SE is just silent in their disagreement, rather than overtly arguing with us.
