I've never been a fan of microtransactions, I honestly cannot remember the last time I've paid for anything like that. As far as recurring monthly fees go, they've fallen out of favor with me, and I haven't actually paid for a month for an MMO since... I believe... Wrath of the Lich King. I don't even subscribe to anyone on twitch and I've spend at least half my time on the internet there.
However, I'm a pretty cheap bastard and I have trouble buying anything in general that I don't absolutely need.
That said, in the current state of the game I wouldn't be against giving $5 for it and once the game improves a bit I might see myself paying upwards of $10 for it, maybe with your 1.0 patch?
I'd like to see you get something in return for the work you've put into this game and I hope more generous people than me feel the same. But I don't want the price tag to scare away any new players either, so it's hard for me to say, I'm not a business man and like I said, I'm a horrible cheap bastard.
