Getting score for taking flags is important. Capturing enemy bases is part of the Battlefield Conquest mode experience and FHSW is still Battlefield at heart.
The other bad counterpoint to lame backcapping is lone score hunting to push the ego. Both are dumb and can diminish teamplay.
Agressively taking flags must be rewarded with score: If it's all camping and defending there is no reason to fight at all
Some have seen me waste my time along with the 1 hiding infantryman I eventually get, or entirely ignoring a particular camping-friendly flag (thus boring the camper to death) but still winning the round. I don't think that their little game is necessarily successful for them in any way, nor fun, therefore they can be convinced or compelled to give it up (they may give it up even without deliberately countering them).
Exactly this is the way to go if you ask me. A lot of maps give multiple flags as an objective to attack. If the enemy is sitting in cover on one place just go somewhere else. If that means that there will be lame backcapping like on Battle of Makin so be it (actually that's rarely a problem on this mod).
