Is there any other way to rank up to legendary instantly?
Based on experience, I, you and all forum member have the same opportunity to reach Legendary rank if they want. Before merit systems existed, all users could potentially achieve that rank only if they had a sufficient number of post and activity even if they only sent bounty report or something like that. However, once the merit system is implemented, spammer and low-quality poster have a very hard time getting merit so that they are stuck in the same ranking even though the number of post and activity is sufficient.
Legendary is the dream ranking for most poster on the forum as it is a sign that we have been on the forum for a long time. There is no instant way to reach Legendary once the merit system is in place, unless you buy it (not recommended). I think we will feel proud and happy if we achieve it only with effort and hard work and contributing to the forum and user.
Note: This is just for fun guys but pretty sure that there are users will going to react violently. Still I can be thankful in their reaction.
Think positive, let's take the opportunity to become a quality poster. You're not only having fun, but also giving anyone a chance to think clearly about how the ranking were achieved.
