An independent mod for 1.7.10 that changes the bad RPG style exponential XP curve to a configurable linear one. It was made due to a lack of any existing mod that performs similar functions for sub-1.8 because of the limitations in Forge's event hooking.
Source code is on GitHub, and any issues should be reported there. Feel free to include it in any modpack =)
