Not going to read all this....
What happens if the MOB runs?
Scrapper fighting MOB, Support/Blasters lets say 100 Ft back...
MOB is almost dead and gets hit with DOT and Runs/TP's/whatevers 210 ft the other direction from the Support and dies...now 310ft away.
In this case no one moved to follow it. Only the Scrapper gets XP/Credit....!??!
Much better system then original....but still...
