the devs came out and stated this.
lb melee hit harder due to single target. straightline and aoe hit for a bit less due to being AOE. look up the recent live letters it was brought up in one of those, or watch mondays with mrhappy he talked about it there as well repeating what the devs said.
not really, people will not learn much if ppl lb trash mobs. How can a tank learn to survive large pulls if ppl just lb them down. Also not every group comp in df has a player who use the aoe lb.
