As the rumours suggest we might be getting Level 50 in the game soon, I thought this was worth discussing:
The XP deltas between levels are somewhat haphazard. For example, 7000 needed for 12 to 13, but only 4000 for 13 to 14.
Wouldn’t it make more sense for these jumps to always be an increasing amount? It might only be an additional 500XP per level (or increase in larger or smaller amounts as the levels rack up), but shouldn’t ever go down.
