This question is for all those who agree ESO ought to remain subscription based. I do too.
However I have to admit that I very much dislike the $15 per month fee, even while I'd be perfectly fine with a $10 per month rate (month-to-month). And say $50 for 6 months or $80 paid yearly. Many of us prefer month-to-month given that some months we may not have much time to play.
I think that $10 ($9.95) per month is also a good price point to attract many more monthly paying customers, who will be willing to KEEP paying, or keep a recurring month-to-month subscription going even while not playing much. I pay $8 per month for Netflix streaming service. And there are months where I just don't watch it much (if at all). Still I don't cancel the subscription. If I was paying $15 per month for Netflix you can be dam* sure I WOULD cancel it when I felt I wasn't using it enough. And then... I might not resubscribe for a long while.
If I'm not going to be getting enough play time in for ESO, I'm most assuredly going to cancel a $15 per month subscription, whereas I would very likely let a $9.95 per month subscription fee carry on indefinitely, even if only playing 5-6 hours per month.
I don't know about anyone else but $10 seems to be my break point for a lot of things. Under $10 and I'm a very easy sell. Over $10 and it's much harder to get me to crack the wallet.
