I'm no game designer. I'd change it in a way that it won't mess with your interface. Out of the top of my head: Maybe something in the direction of making the units camouflaged in cover and slightly faster when out of combat but with a bigger detection radius. This way it still fits the theme of the commander and allow your units to creep up on the enemy, jumping from cover to cover in order to close in (like they did historically at the beginning of the battle of the bulge on which the commander is based) without casting a magic spell where your units suddenly disappear from the minimap.
Slightly off topic, but I think this debate at least partially comes down to which value we want to give to the mini map / tac map. Do we see it as an addition to the normal "direct camera"? Or a real alternative? Do we expect players to be able to play both ways?
What radio silence does in the end just like other abilities is increase the micro tax of the opponent to keep his units efficient, since he needs to check more frequently if they are okay and well positioned. Other abilities (off map smokes and recons) do that too although in a different way.
I think there is nothing inherently wrong with modifying HUD elements of your opponent. RUSE for example did an exceptional job at that. But where I think that this ability falls short is that it does not really work for all players. I see the tac map more as an addon. Nice to have to get a better overview, but in the end I don't use it that often. Other players spent half their game in that, and again others don't use it at all. So half of the ability is either worth more than its price or nothing at all.
I don't know if your suggestion is the perfect solution to this since it could create a whole lot more issues, but it is at least unique and would fir the theme. I like it, definitely worth a try.
I still don't see how 20 munitions infiltration are justified. They can result in a squad wipe quite easily. And by looking at their price tag you can usually afford them without much resource handling. Also they are hard to dodge, because they get thrown around erratically that even if you dodge you still get caugt in the blast.
Yes, I see your point. I don't view them as a major problem at the moment, but maybe that's because the whole commander has fallen out of favor. Maybe some changes to the AoE stats could fix it. Although I'd rather change them to a more consistent, but overall less damage.
