I like the new valour system. It encourages shielders, as it's easier to get valour if you're shielder--->you hit enemy more times than 2h/pole(they kill the enemy more faster) plus you're close to fights.
It's not so friendly towards xbows (IMO it's fine for archers, as archers don't usually oneshot ppl). I kill 3 people(and now I mean more like oneshotting, not "killstealing") and I hardly get 10score, if I hit some1 3 times with my sword and I don't even kill the person there's a good chance I might get over 10 score.
And Vidar, it doesn't matter how long you survive, it's all about hitting the ppl. You can easily get +30score in the first 1min and 30sec if you're good melee player.
Anyways I like the current score system. The point when I start QQ about it is IF the new gold/xp system will be based on score.
