Making Emplacements Decrewable won't work. That will make the faction fall apart, because the Emplacements are such an integral part of the faction's framework.
The only way British players will play other Commanders, is if those commanders are ACTUALLY PLAYABLE.
Most players of all skill levels can agree we have always been having match ups that are fast paced high micro games. It's how everyone enjoyed playing the game and what entertained everyone whom watched the games.
Why is this a problem exactly? Military strategy can be divided into two main functions: Offence and Defence. Before the British Empire forces were introduced; only the Offence aspect of war was present in CoH2. Now, we are able to have a Defensive play style too.
Some could argue that games have been too fast paced; far far too fast paced, usually the fault of gamebreaking OKW.
Back-and-Forth games show real skill. Theres still some balancing to do. But why would I pick Royal Artillery or Royal Engineers when Advanced Emplacement is there? Even if you outright remove the February commanders....Why would I pick any commander?
(Soviets/Ostheer can't even build on map arty in their base sector but brits get it every single game without spending 600mp, waiting til 8cp, or taking any risks.)
You can't compare them. The Base Howitzers are difficult to call in and are anti-synergistic with the Cover bonuses Tommies get. They can't kill anything, even squad members and they don't provide suppression.
