I had a monk sorc at one of my tables. I cannot for the life of me remember what the point of the combo was. Maybe they were trying to use stunning fist to make something sorcerer work. Unclear.
Also dex based clerics and paladins aren't really unsual. Clerics get their heavy armor profs from domains, so not all of them have much incentive to go into strength unless they really want to use a greatsword.
I had a rogue paladin pack tactics kobold in AL. My crits were absolutely brutal.
