I made this account for exactly one reason: to say "Wow, you just totally ruined your game!"
I was actually really looking forward to buying the next adventure this weekend. But now you want me to pay actual money? Uh, no, I only spend money on real games, not mobile time wasters.
I can't even buy characters with gold anymore! Can't buy adventures or characters: gold is now effectively worthless. With gold becoming worthless your replay value is totally gone. There's no way I'm going to pay money for a game that I will play through exactly once, at normal difficulty, and then delete forever. Rewards for playing at higher difficulty are no longer worth the time investment; honestly, saving up enough gold for the next adventure or character was kind of the only reason I was still putting in the time. I feel really bad for anyone who actually bought gold, whom you've just essentially robbed!
If you put gold costs for characters and adventures back in, there's a chance I'll come back, but honestly I'm not going to pay that close attention, because it's just not worth my time. I'm sure you won't care, because you weren't getting any money from me anyway, and that's obviously all you care about, so basically, this is Peace Out.
