I used to get last kill on a regular base yes I was kinda sad at first they made it random but I like the idea tbh, now other players have a chance at also and I have other ways of getting coins I ussually do around 12-14% damage on baal/cerb so I still get a good chunck of coins out of doing baal/cerb, why don't get lower players get a chance at last kill also? they play the game as well they can use the coins also.
