Imperial Guard Command Point battery

I just thought of a better idea to counter unfluffy and un-thematic list, thanks to Wence in Bell of Lost Souls. Since everyone is complaining about how people just spam cheap Imperial Guard Battalion Detachments for those 5 Command Points, how about we increase the tax?

Current ruling is that we can take up to 3 Detachments for 2,000-point games, 2 Detachments for 1,000-point games, 4 Detachments for 3,000-point games. I was wondering what if we stipulate that each Battalion Detachment must be at least 25% of your entire army (subject to change for bigger games, maybe 20% for 3,000-point games)? That would solve the problem of people having 2 HQ and 3 infantry squads in one corner just to camp backfield objectives and do nothing except generate Command Points. Suddenly you can't just bring along 2 Company Commanders and 3 infantry squads any longer. If you want that extra 5 Command Points, you need a fully fleshed out Astra Militarum force, maybe with tanks, special weapons, heavy weapon squads, APCs, artillery or elite Veterans. Sure, maybe people will just bring hordes of Conscripts or spam infantry squads since hordes are the meta, but that's another 320 points that he won't be spending on his main army, and it's quite the hefty investment.

Having each Battalion Detachment being at least a quarter of your army will solve the problems of people just spamming cheap Battalions for 5 Command Points. Of course, I would rather not apply this to the specialist Detachments since it would penalize them too heavily. On one hand, it's easy to fill out a Spearhead Detachment of Leman Russ tanks to over 25% of my army, but it's practically impossible for my Outrider Detachment of Sentinels or Vanguard Detachment of Assassins or Veterans. Plus it'll be kind of sad if I can't ally an Outrider Detachment of Space Marine bikers to my Imperial Guard Brigade all because they fall just short of the 25%. However I can't just take minimal-sized tactical squads of Space Marines and a couple of Librarians for 5 Command Points. This is relevant especially to Imperial Guard's case where you just take minimum-sized Battalions for 180 points. Now you need to take a proper Astra Militarum fighting force, not just 3 random infantry squads wandering in the middle of nowhere and just cowering in the backfield while watching their Space Marine allies do all the work. Funnily enough, it also means the Space Marines don't outnumber the Guardsmen any longer, which is one of the beef I sometimes have with such lists.

I hope this works!
