I think I learned this the hard way, and quite frankly its a little.... slimey the way they do it.
I thought oh let me get my 5 in before Oct ends, so i did. Last night before calling it a night I log in and see new stuff in vault, oh I forgot its Nov 1, awesome! Scroll the list see stuff I like, and.......can't pick any. I guess they call a 'month' 30 days of when you pick it. So if you pick mid month, your screwed til next mid month. Not a fan. It should be pick any 5 during the month, when 1st rolls, it resets. Not 30 days from when you picked it.
I regret 3/5 of my picks now.
Another to the list of me being unsure to keep the $15 a month... But I thought about it for a long time last night, and I played WoW for 10+ years and payed $15 a month... Really all the content from the vault adds up, and $15 aint terrible if you set aside a day of work and call it "Trainz" money for the next few months.
Also, can we use the 25% off from Gold to purchase TS19?
