This game has I think I higher than average age demographic. While I appreciate the OP's suggestion, and completely hate the whole combat logging stuff - it is just a game. You need to be able to turn it off. The amount of times I'm burning stuff in a RES when child A needs a bottom wiped, or a drink of water. What is the OP's parenting suggestion tip? Leave the child? Loose my ship? Obviously if no option is given and the 15s timer removed then than the latter it is. But I would prefer if the game (as it does now) allows me to turn it off.
Don't the none parents ever have anyone call them on the phone??!
But lets talk about what we are really talking about. When you PVP, you want to able to kill their ship, even if they do log out - which is where the "not possible" or "reset timer for each hit" comes from. I'm sympathetic, because the only reason they hit the timer is to escape death - we're all pretty sure there is no convenient bottom wiping needed JUST at that moment, right? The issue is you affect all the players who bounty hunt in RES or elsewhere.
For most players, I suspect PVP is a very small fraction of their time playing the game, while bounty hunting is a very high percentage. Unless you can tell the difference between PVP combat and PVE combat that allows a timer - not sure it works?
Therefore thats my suggestion - PVP has no timer, or like a 60 second timer minimum; PVE has a 15/20s one. That work?
