I have spent hundreds of dollars on early access and beta access and free this and free that. I support companies making great games and really hold close the few that nail it, but I can say that out of all the times I have paid early or bought a pack for beta more often than not I have wasted my money.
You might get to play early, you might get an item that will be obsolete after a few hours, you might get a mention somewhere that no one will bother reading. I thank you those for supporting this game through the dev phase but I will be awaiting release and still then another month or so and you will get a discount.
Please no flame just sharing experience from having sunk thousands of dollars into early or special edition support pack games. I even bought the original $1000 Path of Exile pack only to have another bought out months later with better items, LOL
