5 years, never spend a dime. (7.8GP 3GL's)
It's pretty bad: Have to sweat for 28 days to get the track finished. Always be at the mercy that quests and challenges won't require certain Toons or gear-levels (Gungans next?).
Getting constant notifications for stuff I won't be able to collect. Raising the visability of the paywall.
Requiring more and more time: Yes, we'll get more sims, but we'll also spend more time 'collecting' (like digging through a new market), and they want to have a tighter release schedule meaning more marquee's, more journey's, new AB's, and who knows what kind of Raid they have planned next, since we get tickets more easily.
It probably won't make me quit, but I am now totally resolved on never pulling my wallet. (New quest UI looks nice though.. too bad most of it is wasted on me.. :p )
