Looking through the PE wiki just now, I realized that there wasn't much information on level advancement. Since I couldn't find anything solid, I want to get a general feel how the community feels about it.
1. Should the growth of stats like accuracy, defense, skill points, and health/stamina be dependent on class?
2. Should stat growth be more exponential or linear?
3. How often(if at all) should attribute growth happen?
4. At what rate should a character get talents, and should some classes get them faster than others?
5. How should the XP requirement for leveling up be determined?
