Kill stealing:
You don't own mob, if you are camping it... If someone is faster than you, what the hell. There is no KSing in game atm, you can't KS atm. If somene is taking your mob, you should try to roleplay it, challange him, be faster than he or just leave. Until you hit mob anyone can take it, if you hit him once an than leave for min, anyone can take him > that's not KSing. Ksing is if someone takes mob while you already are hitting him, if such thing happends it's mostly because of offensive spells not set in db as offensive, report it.
PvP:
Almighty DP points.. oh If oyu are collecting DP points, you are jerk.
If you are trying to be best, you are jerk.
There can't be anyone best in this game, there is always lag, connection problems and so on.. And this game isn't CS. Take pvp as extension of rp.
When you die in pvp you aren't suposed to run out of DR and seek the one who killed you to keep annoying, look: Your char just died, it was painful, he had to seek his way out of DR (which should take much longer than it takes atm) and he went trough many things, if he realy seeks revange, he'll get it in few days, not 5min after he bleeded on ground.
Roleplay:
No lol,omg,rofl etc aren't suposed to even show up...
Use [] when you are talking out of character.
Always do difference between ooc and ic, when you get some info ooc YOUR CHARACTER HAVE NO CLUE ABOUT IT.
Always be polite ooc, ic > make some limits to your imagination, you can't have all the powers of the world (best help is to base your char on your stats).
Always roleplay, from mining to dueling...
Fairness:
Always be fair, this isn't singleplayer, no cheating.. in any ways.
Eg > expliting db bugs to killsteal

> potioning your self during fight (yes it's quite unrealistic to drink potions while you are hanging with your swords)
> exploiting any kind of bug, settings, code, rules..
> don't harash people, leave him alone after short time so when he doesn't have time for it, it was ok
we are playing this game to have fun, not to 'break,win against,fight,annoy..' each other
