I have been peked in very diferent situations:
- Other player bring a pk character to clean spot for his non pk characters.
- Other player decides to pk all player that aren´t members of his clan/Alliance.
- Real money Trader Bring a PK to kill players that are disturbing the money farm of his 40.000 Elemental summoner Bots in all maps.
I am sure the 3th option isnt planed to be a part of the game.
In mi opinion, to have a perma red Character its extremly free, if you have a lvl78+ Elemental sumoner you can do it with no risk to loosing ittens, and always you can open gk windows and jump even into towns,and avoid death because he is on a mount.
They need to put a rule that Summoners in chaotic state doesnt make any damage to withe players if they had no weapond/armors equiped. Something like if you are not properly geared with yours lvl you make less damage to withe player if you are in chaotic state. To avoid ungeared Summoner can pk player, and to avoid a lvl 50+ can be peked by a lvl 78+ equiped only with newby Gear.
And another rule for pets, all pets should be just followers if his master are mounted, OR give these extraordinary movility to all other class, like: archers/nukers/healers/tanks,etc; and everyones becomes all happy ussing hurricane, stun shots, agressions,Heals,etc, mounted with 300 points in speed stat.
