I'm going to give you my straight opinion and issue I've always had with the game. That issue is as you said, things aren't always clear. I have no real issue with RNG as long as I know its RNG or can come to the conclusion that its RNG. But on a few occasions, I would have never even realized certain characters like superwoman and Galatia were even in the game until I came to the forum and read in the update logs that something was added for them or fixed for them. There are times I've constantly clicked around none stop just to see the same repeated stuff that leads me to believe I had reached the end of the content in the game. Another example is terr, I would have never realized she was in the game if i hadnt read the update log first and even now I'm still looking for her.
Another issue I have with the game, you choose galatea over power girl, come on now!
Thats all I'm going to say, i need to get some drawing done myself.
