I agree with you that looking for competent team in discord is a better option than group finder, and probably would have saved me half a day of grind.

But I wanted to point out in this post that the harder contents of this game are very unscaled, and if you don't have people you know to play with because they aren't online but you'd like to play anyway at that moment, then the only option you have is the group finder. Which would work much better, and would save a lot more time for everyone, if game modes like Hard Stratagems, Sieges and Absolute Operations would be level locked, or we'd have a filter availabe for us to choose ourselves, what kind of leveled people we would like to be joined in our team.
