I’m a level 22 Crusader, can I find games with people higher or lower level than I am when choosing quick game? I’ve yet to find one and I’ve been playing for a couple days
Unfortunately, you’re going to be stuck trying to find games of people similar to your level. By now, several things have happened. Most people are level 70, and won’t need nor want to spend lots of time leveling up a new character. Plus, the season is 3.5 months old, and seasons typically only last 3-4 weeks before most people have moved on.
You’re best off asking a community for a power level, or just grinding to 70 yourself.
