When you create a new character it is remarkable that you progress according to you level. Many places to get a best exp in your level in case 130- coincide with a monsters in same tasks. For example, lvl 30-50 you can get a very high exp hunting on gargoyle sanctuary, ape city or tarantulas. In case you not hunt with a high level blocker or want a extreme rush you do not have why not make this tasks.
I think it's very valid to make this tasks before lvl 129, cause so fast to make, a lot of taskable creatures get a very high exp and profit compared to other good creatures if u can hunt, if u need a money you can kill demodras at level 100, and after lvl 130 u can make the other tasks to get boss points.
