So from what I can remember (since I arrived during Ao2), it took 3 months for Ao3 (50) to be released. Now, given about a week more til 1.7 (55), thats another 3 months.
Also reading posts that the game was originally mapped out to be up to a cap of 100, thats 45 levels more to go.
Thats 9 more expansions, assuming its per 5 levels. Also assuming that each would take about 3 months, thats 27 months, give or take a month or so, so 2 years.
So it will take about 2 years for PL to truly reach end game? Thoughts? :P
