First was cost, retail is 20$ a month, with a discount you can get it down to 10$ a month for the first year if you prepay, but after that I think the biggest discount is 15$. Don't quote me I am going off of memory.
Personally I am willing to pay 10$ a month. Prepaying is fine. I am not really cost sensitive and could be a whale (heck I am for Star Citizen).
The last issue was skill training. It's a bullshit mechanic to force you to subscribe for years on end because it is time based. You can choose which skills are trained, but there is no gameplay element you can use to progress beyond a lack of skill training. You can't even pay.
I honestly would have converted were it not for a mechanic so obviously designed to keep you pumping in a monthly fee by preventing you from "finishing" the game at your own pace. I like to play games, and then be done with them and move on.
I know my decision making process is different then most. I play zero games on my phone and tablet. I feel like this is similar to the IAP model where you have to fork over the megabucks to get anywhere.
