would be kewl to have front, back, left and right shields and have the ships trying to work with it. I read that they do not intend to have ship components damage (like no more batteries, no more engines, etc...) so I doubt they will change the shield system.
way back a few months ago (and well before I joined the beta) I proposed something like this - essentially an adaptation of star trek armandas fairly cool dmg model. but realistically, this would only make any sense for capital ships, because except for early game, everthing is destroyed so quickly that damage models of that level of detail would just go too much into micro management and would not be all that useful for large parts of the game.
it is really something for a game of a lesser scale I think.
