When logging in 3, 2 and 1 day before a subscription ends we should be warned about this. For example my sub just expired and I have enough cash but not enough money on my bank account and it's 11:30pm for me right now so I don't really want to go to the bank now but I do want to play. I'm aware that we can check our subscription status here on this site but that can easily be forgotten.

I think it does warn you atleast a day before your sub ends.

This is my 3rd time my sub expired and I never got any warning. At least not that I can remember. Well maybe I just missed it.

Perhaps adding a time remaining to the character select screen might be helpfull.
