The time and resources to increase the cap could be better spent elsewhere. It is much more involved then changing a 50 to 100, 200, or 516. The client might not even be able to handle that many characters which needs to be changed. A better character selection screen would need to be created to search through a ton of characters etc, etc. The cost doesn't seem to out weigh the benefits. Great. So a few hoarders can hoard even more characters. What does that benefit majority of the players?
