The 13 heroes has a wide range of level. I read somewhere that PDL was 68 (with only his armor) and Evileye is around 50 (perhaps less if you count she got stronger thru time). The rest are still unknown, including 2 players. Anyone whose beyond 30 is already on the domain of a hero in NW standard. Clementine is already a hero. If you ask me, the average level of the 13 heroes is around level 50.

About Fluder, if we follow the "1 tier per 7 level from the total level of magic related class" rule then:

[Tier 1: Lv1-7] [Tier 2: Lv8-14] [Tier 3: Lv15-21] [Tier 4: Lv22-28] [Tier 5: Lv29-35] [Tier 6: Lv36-42] [Tier 7: Lv43-49] [Tier 8: Lv50-56] [Tier 9: Lv57-63] [Tier 10: Lv63-70]

Fluder 36-42 is still within the realm of heroes. Same with Dominion Authority which coincides with the anime chart.
