I know that higher ranks of strength let you pile on more armor, as well as increasing the damage dealt with normal attacks AND ram. My question is this: how effective is it to boost up endurance, as far as survivability is concerned? Is a transformer better served by having high strength and armor, or is his durability in a fight improved more by the increased HP of high endurance? I.e. who can take more of a pounding, the robot with 10 strength and 10 tons of iron armor, or the robot with 10 endurance?
