Yea. Adjusting the experience required each level was a challange. The idea is that on the first level you would need a lot cause its the first curve. To learn the mechanics, you will get to know and explore the opponents, explore your skills, and then, find a way to grind efficiently, and then grind. If the XP required for the first level was too low, this curve could end prematuraly and you would take out you a skill you are not familiar with. The second curve is just grinding and taking out skills you don't use. Then the last is just trying to keep yourself alive.
But yea, you're not the only one complaining about the grind on the first levels haha. I think It could be a bit smaller. But in my mind i thought that farming the dragon 10 times wasn't too much for the first level.
But yea, thas for the feedback!
