Does anybody else see Herald's overpay as, "You want to win this split so badly that you're probably going to overpay anyway, so here's an extra treat for when you do"?
I usually see it as "you want to win this split so badly that you're probably going to overpay anyway, so here's nothing for you when you do so at the top of your shuffle".
I think Ironmonger is stronger than Herald in general. Herald needs a lot of work to be powerful, Ironmonger is powerful right off the bat. I think you basically never ignore Ironmonger, but there are times when you can ignore Herald.
