I would argue that there is no actual skill issue in FL, because there's only so much skill you can show with such a limited amount of buttons. What people lack in FL are all the related knowledge to function properly in large-scale PvP, such as spatial awareness, map awareness, positioning, the ebb and flow of combat, etc.

If people put in an effort to learn all the FL-specific things that they need to know, the quality of matches will definitely go up. That's why I encourage the people who complain about DRK premades to play DRK for a bit, learn all the engagement methods a DRK can use and learn which one of them gets punished the hardest. Once you learn enough about DRK's methods, you'll know when a DRK dive is the most likely to happen and how to position for it, which greatly reduces your chances of dying to it.
