If STG launches new level cap, they obviously don't listen. We don't need an additional 5 levels to add 25 stat points and 5 skill points to add to where (?).

All these additional stat points can be done through items. A 5th skill slot or additional / expansion in skill upgrades will make it more worth it for 5 more skill points.

Ultimately game balance. Those who keep asking for a level cap, wake up and look at the bigger picture. Game expansion doesn't require a new cap.
