I was on Ark and decided to raise a new skill. I picked up a Carabok kill quest and was shocked at how fast it went up. I got to lvl 5 right as I finished the kill 1000. Now Im back on Caly and just finished the kill 500 puny quest. I think I have maybe gotten 25% of level 5 done. It just seems like its moving very slowly compared to how it was on Ark. Why is this and should I go back?
