This is mostly a PvP issue. You really can't mess up with these in PvE. So during one match I can pop in and out of cover, down opponents with relative ease and heal teammates without much issue. Travel time on the projectiles can be tricky but I love these weapons. Then the next match rolls around and not only are my shots whiffing badly but they're barely doing the intended damage when the shots do connect. Now I figure maybe it was Range or the way I was moving, making the projectiles less than reliable. Reasonable way to look at it. But no because I'm not doing anything differently and it went from one map with larger, open areas to another with a similar environment. I know the projectiles don't track a certain point but that's not what was happening. I can only assume that connection and lag are disabling these weapon's ability to function.
