well...if you think that it is terrible for getting 2 points...try living in my demomans shoes, I even get 3 points for killing players around 80.000 points...
usually I just see gets 2 points for killing, with meleeweapon modifier x 3.5 or x 3.0
Lose 25 points almost all deaths when players have under 30.000 points.
If you are that high in the rankings, you should destroy sentryguns and dispensers, both 5 points, ubercharge 5 points, medic kill assisted 4 points and domination 5 points. Also the god-like 11 points are very helpful.
I think I need an average of 10 points a death if I don't want to lose points for getting killed.
But getting too obsessed with rankings is really bad for the game, trust me, I am very competitive and my goal was to get above Dev/Null, (since the others nini and salty are like 25.000 above 3rd place) I can now relax more and don't care if I die, still hates to have a critdeath but much more fun to play if you aren't worried about stats.
