I agree with this, especially with the new update to the free version. XP was nerfed and it very tedious having to be over Lvl 200 and have the XP cost be around 20k with monsters only giving 200 to 100 XP.
Wait so you're saying the exp in 4.4 is less than in previous or future versions? No wonder it feels tedious trying to level either myself my current character is at the 1000's or a partner. I hope none of the versions after 4.4 keep this feature as it makes the bame harder to enjoy since growing is the main focus
