The IW engine sucks because the firerates are tied to the framerate (a big reason for Attack of the Clones)

This engine sucks because fire affects lag too much(no flamethrower >:c )

This engine sucks because this game is NEVER at 60 fps like they so fallaciously[sic] claim.

This engine sucks because it runs on network rates that became obsolete DECADES ago.
