Yeah, I've only ever spent $5 on PAD. I'm not too worried about the REM. I'm only playing to have fun and enjoy the experience. When I stop I'll probably stop playing, too.
I know I come at PAD from a different approach, and it's because I played over a year ago and then stopped when I hit a wall about thirty or so days in. I pulled Yomi but this was before awoken skills and ultimate evos. I got tired of the grind, pulled during a Godfest using all the stones I saved up and got absolute shite. I was so pissed I quit!
Earlier this year I decided to start again IF I got a good first pull. Before going to bed if I had time I would do one run through of the tutorial. First one was bad so I deleted it and went to bed. Few days later, same. Few days later pulled Kirin. I had no idea whether she was good or not until checking the op, hah. The point is I wanted a no stress approach to the game. When you follow this thread it sometimes sounds like the players are in an abusive relationship. It's really weird! I recommend avoiding that. PAD isn't inherently unhealthy, but the way some people approach it is.
