Term "new ability" can be used not only to new content but also old units/abilities that were completele revamp. Commander doesn't have to have any new stuff to be desirable. Main key is to make good composition of slots that will fill the certain gaps that faction lacks. So overhaul abilities like Hold the Line or TigerAce (for example modify to be Tiger Command Tank) even though they are in game, they will be something new.
Even only slightly improvements to certain units for example panzerfuzzilier or assualt grens (but with diffrent effect than JeagerLightInfantry) will be like renewal and restore old stuff and will give players feeling of fresh a breath of wind into the gameplay.
But to all players who came up with commanders proposal made only with already existing abilities, plz remember that doesn't mean that doctrine will be easy to create. Abilities meansioned about like HullDown, TigerAce, British Hold the Line etc. They need complete changes and have to be make from scrach. It's often easier make something new that fix it. Generally speaking it doesn't matter how many "new" old "old" abilities will new commander will include. Most important is how they gonna be implemented and balance.
Let's be honest, all commander proposal aren't perfect and they will have to be slightly revise. I hope balance team will contact with those people and suggest them highly welcome improvement of them before the final vote.
Agreed.
