I use a bond monk for things like 5 man FoW runs. In DoA bonders are also used. But less now due to ursan groups.UW in full groups. But as stated above with ursan, not needed. These are the more common places. If i left any out i'm srry.
You don't need a bonder for FoW. Maybe in the UW since Aatxes hit pretty hard but I think a normal protect monk will keep the worst off of you and do more good for the party.
