prove it L2P, wit an opinion but back it up and no if i have sometin to say about yur Artillery and Tank idea? no a tank is stronger, think about it wit tanks u have lots of mobility AND tanks can have artillery mounted on them, if yu want proof look up the M110 Howitzer (it's a light artillery tank, kinda like diablo)
and it just depends, man
but yu are right wit yur ideas L2P but, Mephisto was the first to be captured by the Horadrim AND he was also the first of the Prime Evils to be vanguished from his Physical form (in other words he was killed first) hope that is understandable and proves a minor point
Diablo by far is the most evil, I mean come on. he corrupted King Leoric, made him turn on his own town. He used trickery and deceit to drive people mad. He made the Warrior evil by controlling him, and took over his body. Ya know the Wanderer.
