Conversely, get rid of K:D. Anyway here's a few issues:
1) Over kill exists [ie, not all hits are important->Simply hitting somebody is not important]
2) Taking a blow [blocked or not] in place of an ally, allowing them a free hit, and he kills an enemy, that is pretty big assistance
3) Dehorsing somebody and having a team mate kill them when they're down is pretty big
4) Holding attacks to force a block is useful
5) Forcing a shielder to ping pong is also very useful
If you need a score to tell you how well you're doing, something's wrong.
I totally agree. But people want others to recognize their good teamwork, and they probably don't feel as useful as the guy who's constantly at the top of the leader board.
Hoplite/spearman and archers (and horse archers) really come to mind here. Especially so after the archer nerf. These are two very important support classes who really don't get a lot of kills compared to other classes, but are just as important, or more (for obvious reasons).
When I'm dismounted I'm not quite like a fish out of water, but I'm not nearly as "powerful" as on a horse. That being said, I can be just as useful (or sometimes more) even though I'm not even getting half the kills I would on horse. I take hits with my shield, I force other people to block by swinging at them, and sometimes I even get a hit in.
Not really. Then no one would have no indication at all of who's good or not. For instance, you wouldn't know if there were really good cav raping your team, or someone like chase tearing people apart without paying close attention to the kills list. So you wouldn't be able to focus more attention on them to help your team.
This is true for me since I'm not in the thick of it every round with our ground troops. I usually don't even know that there's someone on the other team raping us unless I look at the score board. Yes, that is partly my fault, but people like horseman, or I imagine even archers, may not necessarily know who's mopping up our team. Having a score board is nice, but it's also really un-realistic for me to get the heads up, without actually having to witness the destruction. It's nice for me being on a horse though because then I know who to look out for, and who to aim for when I'm couching into a crowd of enemies.
