Most games would necessarily have to pivot from total destruction of enemy army to objective based, which is good and makes these games far more interesting. You could pick a game mode where the objectives of one side are not even known to the other, and that gives them an advantage, even if their army is considerably more expensive points-wise.

Unless something like this happens, though, you’ll just get people only playing the big guys with cheap points. Already the Ultramarines are considered lame and bland, but now everyone who picks a Space Marine army will just go with them because, well, they aren’t at such a terrible disadvantage.
