Ah... but imagine if they were, or bigger. A full sized war with titans every match. Bump up the players to about 15v15 keep the spectre's and grunts.... maybe even amp those up a bit.
Got people and titans trying to hold lines and control the map.
It would definitely change the feel of the game a bit, (towards team work.) probably away from those whom currently enjoy titanfall the way it is now but it would be fun on a bun.
