[The Panther]

It is done on purpose, I think, forcing you to put a ton of gems at risk if you don't know the answer for sure: Is that third queen gone or not? If I ask, can I believe what the other players tell me?

It does make it far more exciting, imho. I would certainly vote to keep it just as is. In a current game, I had my ally tell me to not bother summing an air queen as he just lost 50 gems trying. Good information for sure.

Same for the dispel global thing: Now, how many gems did that turkey put into that Gift of Health? Will an extra 33 be enough or not?

I think the reason that this is not done for mercenaries is because people would be loath to ever bid on a merc if you might lose all your precious gold for some wimpy merc's who will just rout and die anyway at some point.

An air queen, on the other hand, is worth the risk.
