How to implement this: Consider four subjects: two on each team. Team A is subject 1 and 2, team B is subject 3 and 4.
Suppose Subject 1 is shooting at Subject 4 while Subject 3 is looming behind, Subject 2 can kill Subject 3 but Subject 2 shoots at Subject 4 instead and then Subject 3 kills both 1 and 2. This is a way too common scenario.
My point to promote teamwork is that if someone attempts to take down someother’s business after they already severely damaged them, the third partying teammate would get only half the SL and a maximum of an enemy kill assist, and if the teammate who could register ANY hits on the same enemy eventually gets critically damaged, severed or killed in the span of 15 seconds the gain will be actually removed and punished with half a team kill’s price.
Third partying would be at a loss and this would make people focus more on protecting their teammates instead of gathering as many kills as possible.
