You may have had this suggested already. In the ratings I was going over the balance of Positive, Negative and Neutral tags. There's more negative tags than positive and neutrals combined.
Another positive tag you may consider is, valiant. Also consider giving the person rating a player. A comment area of 'x' amount of characters. Twelve or 18 perhaps should be enough to leave a comment like; up n coming, memory lapse, puts cart b4 horse and one I would have said. "well played" "truce memory lapse".
normally i would move this to suggestions or discussions(if thats your fancy)
but this is just a nono. we had a system with comments that people could leave. it was horrendious and tedious for mods who got overwhelemed with reports about someone names my mother this or that.
ratings dont really matter in the current cc environment, once you have enough, it stays about 4.7 or higher (exceptions wil happen) but even so there were nearly daily reports about the ratings and the tags...
this idea will not fly as long was there are wars in the world, aka never
