Im honestly convinced they just "ported" over what worked on the FB3 engine from previous titles then just went "that will do"
Im no saying it to be nasty i honestly just believe they decided to spend resources somewhere else and they deemed what they had "sufficient" when well to alot of ppl (myself included) the choice was far far from sufficient. but i can understand the choice to do so tbh.
I cant begin to imagine the amount of work BioWare had to do to try an get a RPG to begin to work on a predominantly FPS built engine an again can understand how and why alot of things just had to take a back seat, because for me if i am honest alot of things did take a back seat and hairstyles was one of them. but well a game had to get released an for me i think wee still got a good game.
Its no small feat to learn a new engine and build new tools for it to get different genres to work on it that it wasnt built for an then on top of that to build a game along side it all.
the guys an ladies did well an wee prob see the benefits from the work they put into it not just in the next ME but all EA's titles this gen.
Im disappointed in the number an style of the hairdo's but im also appreciative of the undoubted amount of work they have done an have utmost confidence the CC an all things concerned with it will be continuously enhanced throughout all BioWares future games
