if anything HP level should be effected by the amount of NPC baddies you kill in missions or the amount of missions you do.
newbies are a precious commodity and fuels the future of graal yet we slaughter them like fish without mercy for HP/kills/ pocket change.
ive done this myself on UN when i was younger just piss off newbies to the point of they swtich servers or never come back to graal all so i can simply get more kills to show off.
