Wouldn't 'Epic' and 'War' films make more sense grouped together?

Make more sense to group together as a forum rather than Epics and Disaster movies? I just feel there's a lot more crossover with those two genres (and heck, I think even AFI seems to consider to be the same genre). Case in point, many (if not most) epics have war involved somehow. Case in point is "Lawrence of Arabia". Undoubtedly considered an epic, but it is also recounting events of World War I. And just in general they seem to converge more when it comes to themes and story points.

So does anyone else agree that if Epic were to be grouped with another genre for a forum that that would make a lot more sense? Just curious to see what others think.
