It depends not only on the fandom but what the other rper or u are looking for.
For example: if i asked for a roleplay of batwoman but i also mention that the person must be caught up to current season or know the character well enough to rp them, they would have to have experience rping as her...
being ghosted twenty times well now its a bit more than twenty
and they never reply after my list of ideas for the character pairing
or they say after a day or two "im sorry i took too long to reply but im not intrested or i have too many roleplays currently to add another"
I wish there was more roleplayers that could rp not just the main character perfectly but the other characters too along side you. That way your not the only one who has to rp your character, all villians or creatures
While they only rp one.
