Ranged units have a 2 tile attack radius. Melee 1 tile. (on strategic map).
We're listening to see if people want this or not, we're currently neutral on whether all units on the strategic map should only get 1 tile.
[I wasn't able to get to archers during .803]
When I right click with my stack selected, they attack the units adjacent to them, but do not occupy the tile afterwords. Is that what you mean by melee range = 1?
Can you right click with an archer selected on a unit 2 tiles away and get auto-bombard right now?
FfH: Age of Ice had a bombardment mechanic with 1-tile archer range, it did mean that you needed to mass archers to control larger stacks of enemies.
I think a charge mechanic would be a good way to limit strategic archer bombardments - but as I said, I'd rather that archers not have siege at the strategic level, saving that for tactical battles & factored into the autoresolve.
