I can understand that the pricing looks frightening at first, but I guess it is less of an issue than many think. The alternate character version cost 6k or 7k gold in the store. If you buy the daily gold package (max 6k gold per month) for less than 5 $ and use challenges to boost your gold income while playing, you get easily one alternate character in less than a month without any major grind. If you're willing to grind a bit, you can speed this up substantially.
So it is only expensive if you need all new versions right now! Aim for one per month and you invest only a fraction of the money and also get a long time goal until Obsidian give us something new to save our gold for.
And I'm sure there will be discounts later for the bundles, so just be patient.
