You missed the second line of what I wrote
So you pull a guard into a tower field, guard returns to spawn as it would now.
People solo lvl 300 city generals they don't need help from guards
s10 don't know never bothered with that instance, it's heavily farmed by twinks anyway
s13 environment damage (gates etc) cancels all loot and xp
Calming after agro resets the system.
Neither of know how much is on someone else's plate, or what is simple to implement or not
But given your past experience and big picture view, what is your solution to kill stealing ?
