warrenborn has a pdf with all the old WizKids scenarios, so maybe look in there for a few that catch your eye. Depending on what units you have, you might be able to try combining factions with different paradigms (Rasalhague with Clan Wolf, etc). Artillery support can be fun, depending on the artillery and the scenario. The top-end VTOLs are probably game-ruining unless you have a deep enough well of units to counter it, but it sounds like you don't have enough units to degenerate into the meta that the game turned into by the end.
