Well it may not be a top priority but it would be a nice touch as a feature, plus in comparison to most features they need to add/change I don't imagine it would be to much hassle (I might be wrong). If you're right handed you may not understand as barely anything isn't automatically right handed, but to me it just feels somthing is odd in a way whenever it sais 'offhand' and its using the left, I'm not an massive gamer and so havn't gotten to the point I don't care about features that make a character more personal for example a leftie...
I'm sure I'm not the only one who feels this way and as with everything with life there are people who dissagree, I'm just voicing my opinion..
