Suggestion 1: Don't spam email your distribution lists informing people to play this game when it's not even released yet (NOT EVEN IN BETA!!!). Wonder which genius executive came up with that one.... Let me be clear, if the email clearly stated that this was for an alpha test that will require you to pull out your wallet at least I would know what I am getting into. How it is currently portrayed is not accurate whatsoever.
Suggestion 2: Don't require your alpha testers to pay ~$50 USD to test your alpha. I mean come on, seriously? Not sure what needs to be explained here. Expecting people to pay $50+ just so they can alpha test a game is beyond ludicrous (HINT: Alpha/Beta testers are doing YOU a favor. Not the other way around). Dropping it down to ~$30 USD once it's in beta is just as pathetic. I am well aware companies have to make money to exist. This game is already heavily monetized in every way possible. An initial purchase, optional monthly subscription, and paid currency to top it all off.
Suggestion 3: Putting all this aside... at the bare minimum you should probably have a client that actually works. I downloaded the install exe off of the website, let it run, opened up the client and boom "ERROR" in big red letters with no indication on what the problem might actually be. And no, it's not my computer or internet connection.
All-in-all the game concept looked pretty intriguing and full of potential which is why I hit "play now" on the email in the first place. I was then quickly disappointed when I found out what the email really was: an ad for a paid alpha test on an already heavily monetized MMO whose client won't even let you open the game. Such a shame.
