I was going to do that (the static) anyway. Plus, anything outside of your own Domain (e.g. with fog of war) will require radio to stay in contact... It won't be too awfully hard to keep track of where you lose normal contact and switch to radio.
This WILL, of course, leave transitional (e.g. into/out of Domain) movement a bit confusing (currently the engine simply crashes, I'm working on that) but I'm sure I'll come up with something.
Lastly, I've been thinking about this radio thing and for all of you who clamoured for squads... Looks like we'll have them. Sort of.
My new idea is this: while in Domain, each unit can be controlled individually. Before a group can leave Domain, one unit has to be equipped with radio stuff and several units "assigned" to it. While in the field, you can directly control the "commander" unit, and relay general commands to the rest of the group.
Electronic countermeasures are finally important, and the "magical scouts" I have designed for each faction will be far more useful. Especially think of a scenario where you don't have the aformentioned "seers" (due to an attack, maybe) and suddenly one of your field units loses all contact. You have no idea what's going on, it could be a minor radio malfunction, simple communications jamming, or your soldiers could be reduced to smears on the ground.
Thoughts on this one?
I like the idea of having personalized commanders in the Domain, which makes it more scary, but then having a squad in the field for practical reasons. Otherwise it would end up being more like an RPG. The radio idea could also really heighten suspense and make it so you're never quite sure what the enemy's doing until it's too late.
