I would even be ok with just being able to kill them off. Doing this will free up hospital space that is very valuable if you get caught offline as the weaker Troops are injured first .
Kill them off? Find the biggest wall in your realm and send a march with just your unwanted troops against it. Use just ONE dragon and select the weakest one.
It would also be nice to be able to convert unwanted troops into something useful, like upgrade troops or dragon food, as the amount of time and effort that goes into training troops just to kill them off is a waste
If you can make your march .01% (might be .001%) smaller then the person you are attacking, ALL of your troops will die in one hit.
Not really. I sent my remaining 130k t1 and t2 troops to someone with 5 billion might and they got snuffed in one pass.
