I think that the majority of players (and I could be wrong) would prefer a game that lasts longer than being able to play through in a weeks time and be done with it. At least I feel that way and I'm only one of billions of people in the world so I know others share that thought.

And looking to the future, knowing there's a ton of updates and content awaiting B*, I would say the leveling rate is fine. Speaking for myself, I'm in it for longevity. Knowing how Pocket Legends has evolved and grown into the beast that it is, I know SL has only just begun. I think it's safe to say that STS is also in it for longevity and they have some great things coming. Be patient, play when you can and expect new content in the future.

Trust me, running through an entire game in a week or less and having nothing to do with it anymore after that leaves me with a far worse feeling than me having to grind to beat a game, or in this case, reach the level cap.

Hang in there.
