Atm, Frontline and Liberation modes of this map share the exact same objective placement. It's not a problem really and the map is balanced of both modes, but what if the objectives on Liberation were very spread out, just like in Somme Liberation?
B would remain the same, perhaps it could be a bit bigger, but A and C would be the first trenches of both factions (trenches, which are nearest to the spawns / HQ's). This way those trenches could see some combat and the map would get additional replay value.

To remind again, this is an alternative change that doesn't need to happen and won't fix anything, but it would be just interesting to test.
