So by all means, give us an out, but it just seems like yet more money grubbing. If you want to help then let any account who has been through the content once opt out of doing it again and again, but don't make them pay. Not just bc it's shameless money-grubbing, but bc the community doesn't want to be stuck with people who don't know how to play AT ALL ending up in ques unable to play their class and annoying other players. The people paying to level will get bored and quit anyway and a lot of good, non-cheating players may feel like the challenge is gone if you can just buy levels and may quit too.. which means you'd lose a lot of subs.

tl;dr- This is a HORRIBLE idea and most of us hate it and it will probably lose you lots of subs vs losing people who wanted an easy ride and have a short attention span to begin with, who will probably quit in a month or three anyway bc it's too hard. Don't do it.
