After having played some 10-15 hours in the game everything seems awesome except I feel the shields could have greater visual presence. Perhaps adding some settings that enable you to change the opacity of them (as they feel a little transparent - as if anything can get through) and maybe even changing the colour from a white/greyish one to a more bluer tone might do it some wonders. Perhaps even making it optional so that your shield's colour coincides with the colour of your units for that game.
Any other thoughts on this?
