Other than Archer Fighter and Gunslinger, is there any way to use combat maneuvers at range? (Looking specifically for feats--but am open to anything.)
As for feats, the whip (and possibly net) feats are the only ones I can think of, and even then it's less using them at range and more using them with reach.
The ocean subdomain lets you doo push or drag and the air subdomain gives you a line effect bull rush. They are not feats but could be fun for a Cleric to mess around with.
