I don't get the fascination with 1 to 15. That was never difficult to get. The trouble for me was always the scaling.
Level 1 I kill a level 1 get 200 exper.
Level 10 I kill a level 10 I get 200 exper.
Level 30 I kill a level 30 I get 200 exper.
Levels at the bottom are easy. It's when you are up there looking at 50-60K exper per level and you are still getting 200 exper. In most games you drop back a level or 2, you lose 10%? Here you lose half.
Even Levequests, you only get 2-3K at 30 and you are looking at half a million for that tier. I'm sure there is some magic railroad to 50 that I didn't try but I'm pretty sure there is a reason I didn't try that magic railroad. I either A: didn't want to or B: it wasn't very intuitive.
1-15? It's 20-45 that I find to be a wasteland.
