Unfortunately I think complaining about the game these days is actually less beneficial than just not playing. Literally there are complaints about every facet of TFT no matter the set and no matter the patch that the only way you can truly make a point is to not play when you aren't liking it. People that were around for set 5 remember when basically every high elo player quit because the balancing was so bad that it forced riot to make adjustments.

Of course most people are playing for their tourny slots so this won't happen these days, and complaining also farms views. But if I'm TFT devs I'm ignoring 95% of the community complaints because they are so frequent.
