the title caught your eye didnt it?
Alright so onto point, for when the real combat and fighting/pvp worlds comes you should not be able to identify a person unless they allow you to do it. hence play as assassin.
They know me as Zouls, i am one of the best dagger smiths in the area and is known for that, i run a small shop where people come and buy stuff at day and i always have a stock of materials for use
but then when the night falls over the city i closes up shop, pick up my daggers and grab my hood.
i enter a pvp world where people are playing and fighting, and i hide and scout, suddenly i see a person fighting alone at night, bad idea, i jump down behind him and stabs him in the back, not enough to kill him but the daggers are made by me and contains a slowing poison so before he can hit me i jump out of the way and behind him this time finally finishing him.
day time comes and i can gladly open up shop again and start selling crafting items, nobody need to know where i got my materials do they?
and while the rumor spreads of a master assassin i will smile ever so slightly since nobody have the identity of the assassin.
on the other hand if they can identify me by no logic and just by seeing me then something like this would never be possible…
we are allowed to dream though
