Hmm, how about introducing "perks" that you can "buy" with 1 skillpoint, like:
"Commander": doubles volume of voice commands used by this player and makes him unmuteable
"Orator": doubles font size in chat
"Ladykiller (only for men)": Women only do half damage to you, if you type "yo baby" in the chat max 10 seconds before being hit
"Black Widow (only for women)": if you you hit a man, and he doesn't manage to hit you back within 20 seconds, he is killed on the spot
"Vegan": you don't eat meat. As a result, animals respect you more than other humans. Therefore you don't take horse bump damage
"Troll": whenever you kill someone, they are kicked from the game. If they rejoin and manage to kill you, you are banned for 1 day
"Chastiser": if you hit someone with wooden stick, their view is switched to first person and their vertical view height is restricted to below eye level
"Horse slayer": if you kill any horse, you gain +10 health. Horses do +50% bump damage against you, because they can smell you ate one of their friends
"Ichtyoid": if out of water, you lose 1 health every 10 seconds. In water, you heal 5 health every second
"Radiant one": you give off light like a torch and heal friends 10m around you for 1 health every second. If it rains, you lose 1 health every 10 seconds, give off smoke instead of light and don't heal friends but cause a random coughing sound to be played on every friend within 10m every 1-3 seconds.
"Gambler": if you are qmled and hit m exactly at second 29 after having been qmled, you get a free multi.
