Two things I have ran into that I hope gets fixed.
The first one has to do with unit movement.
It may have been discussed before but the player needs to verify the path that the program chooses to move units. Usually the routes are pretty good. I find the biggest problem with unit movement is when the units need to cross the same path as other units. First, why if the units are passing each other they can't use the same tile space to get from point a to point b. As long as units don't end their turn on the same spot and are friendly, they should be able to cross paths.This actually brought something else to mind. Is there a way to combine groups that occupy the same tile with out moving one off the tile then back on again? This would be a nice feature to add if it can't be done.
The other issue is to be more transparent in what units are able to do and not to do.
Example: I had a unit that casted Titan's Breath. The first cast the unit was knocked prone and got back up right away. I am not sure if this unit is immune or not. I assumed it was. I casted the spell again and the units stayed prone. I was happy at first because this unit was tough. The part that got frustrating and weird is that even though the unit was prone, when I attacked it the unit was able to counterstrike. So visually I watch the unit on their stomachs get up to counterstrike and then lay back down on their stomachs again. It did it after all four of my units attack it.
In the second issue, what I'm trying to say is that if the HUD screen for tactical battles could display a user friendly stats of the attacking unit and the unit that will be defending. This will help in deciding what to do in battles. This will also help in finding bugs. Right now, I can't tell if something is a bug or there are modifiers to units that make things act differently in different situations.
Some suggestions are to add: % chance of damage, % chance to resist spell, can the unit be knock prone, range of archers(should an archer be able to shoot from one end of the map to the other?)
