#1: I've been thinking maybe making support mode actors weak against melee mode actors and vice versa wouldn't be such a great idea after all. Maybe instead support units could be slightly weak against melee mode actors but can hit any target, while melee type actors can only strike nearby targets, but introduce no particular weaknesses while in that mode.
#2: I had initially envisioned movement to be something that is sudden and near instantaneous, but I think it would be better if movement was somewhat gradual. I also thought that maybe it should require a full turn to select a new target (where movement would automatically take place) before an action could be made, but now I'm double thinking that as well. What I'm imaging is that (for a melee mode unit) if you select an action and then choose a target that is out of range, the unit will automatically begin moving closer to that target, so it will take longer to execute the action than normal since the distance has to be traveled. Maybe the actor's stamina rating can somehow determine their movement speed in battle?
#3: For support unit movement, well they don't really need to move except when they are switching between melee mode and support mode. When switching to melee mode, they'd make their way to their target. When switching to support mode, they'd retreat back to the support lines before they were able to take actions there.
#4: Perhaps a melee unit can not move if it is being targeted by at least one other melee unit that is within range, unless it is given a retreat command to try and escape from its engagers.
#5: Now a problem with this gradual movement is that there's not much screen space, so we'd have to move the actors very slowly (even though they should be running) so that there is a significant cost for movement in battle. Or, maybe what we could do is expand the battle field. Imagine if our battle background was 2x-4x as long as it currently is (height unchanged). We'd still show the same view perspective (and maybe allow a zoom feature), so you couldn't see the entire battlefield at once. The camera would automatically focus on actors taking action, or the player could scroll left or right using the two left and right trigger keys (hah, they have a use after all
. This would also make it possible to have absolutely huge battles with 8 or more characters and maybe upwards of 20 enemies for large battles.
The major draw-back to having this kind of feature other than the limited view of the battle field would be the battle backgrounds, which would have to somehow be made to cover the entire background (they are already 1024x768 images, so making one 2x to 4x as big is a huge, huge cost).
