Why not have release some stats of kills/deaths/wep types/builds/playerpops/generations etc, perhaps even connected to the data-set?
If you would connect K:D Ratio and W:L Ratio, Class and player experience represented by xp/gen you could make some stats actually useful for deciding the battle-power (or siege, but that's a bit different stats) of a class, or even the exact weapon or armour..
My prediction is that from a pure K:D ratio perspective or you would probably find pure 2h and polearms.
This is because most players want the extra challenge of manual blocking after some time, and because those classes reward and punish your personal skill the hardest, and therefore are the most satisfying to play for an Elite player.
Now, if you take playtime/XP of the player into the calculation you could see how a 1h+shield with the same game-experience as a 2h does it. My prediction is that the shielder would come out on top, simply because the shield makes you die much less.
Also, by counting in W:L ratios of players you could get a measure of team usefulness and uselessness. Finally all those non-lethal but staggering arrows in the back of someone in a duel can be counted for!
I do believe it should be possible to calculate this.. If we could dig up the right data. This data might not be available however, and may need to be recorded somehow.
Give it to the community, and I'm sure some clever folks here could make good use of it, making it presentable in an informative way. I remember back in the day chadz presenting stats of what class killed the others the most, how the classes were distributed among players, what class had the best K:D Ratio etc etc..
We could get information like:
What is the most effective noob class for K:D ratio and W:L Ratio?
What is the most effective average xp class for K:D ratio and W:L Ratio?
What is the most effective Elite player class for K:D ratio and W:L Ratio?
What is the best class to kill a shielder with at different skill levels?
What is the best class to kill a 2h with at different skill levels?
What is the single weapon with the best K:D ratio overall? What is it mostly beaten by?
etc etc, use your imagination..
This information is important to give to the players of cRPG, because game balance is a kind of self-balancinga market. If more cav pops up because its currently OP, more people will bring pikes etc, in order to survive. A well informed market is a better market, with better transparency players are able to make better decisions, and to truly see what is OP and not. If something is truly OP without counters- it will stand out in the stats quicker, and devs will be able to correct it faster.
Besides, it gives us something to pass the time with before strategus..
