The way I see it in an mmo and you want to roleplay, is that you can not avoid meeting a player that you dislike because the player is out of place story wise or the player is behaving poorly in chat, but that is the same as in any other situation. Picture yourself not understanding what they write in chat or that you saw another lunatic, plenty of those in tes
Why would everyone be tied together in a web of destiny leading to the same end?(If I understood that correct) Are you not tied together when you play together, If you work or go to school are you bound to your classmates or workmates for an overlapping bigger purpose?
As arieste said alot of games are dumbed down yes absolutely agree, but one can still find the rp in it if one want to. see mmos as a big time rp compared to more strict small rp where everyone has a set character that everyone know. It is more about how you portray your character, not about how you will affect everything around you.
Think smaller in the beginning then it may grow, maybe you find a guild to rp with along the way or you find one before you start to play that want to have set characters/story and know about the other players. Or you forever rp in random groups you find along the way.
