Have you bothered to invest in everything? Doesn't accomplishing more things award more experience per chapter summary? Sure the ch1(delgar forest) respawn area won't do much. The respawn area of ch2(aram border) and ch3(dwarven tunnels, maranite camp desert) are worth it. Being able invest in things will bring up rp for everyone with different values( sometimes a negative). The 4 times you go into the dimensional space, you're being awarded 5k-6k per group you defeat. This recent update, some defeated groups gave out 13k and the special were higher. Between lvl 50-60, the requirement to level up is 20k. 61 and higher is 30k. Well then, I'll keep playing my way and you can stick you yours, because no one can be right against you, only with you, that isn't at all an open or honest view I'm willing to invest in.
