^My initial post to this thread is above and was under the title of "Any way to implement a one-time purchase subscription flat fee like ESO or GW2?"
I think everyone pretty much pointed out that a full on "BTP" model like the afore mentioned games could never happen, and probably never should... However, there is a much more valid and attainable suggestion to be made. (Thanks for the awesome constructive flow of discussion!)
I propose adding a "lifetime" subscription option to the current hybrid system.
Could this be the solution to a possibly non-existent problem? I know I would love to fork over a large sum of money for a lifetime subscription, but some people just prefer periodic subbing.
There would be serious pros and cons to adding this in, but it is indeed a topic worth discussing and considering.
