Another way to look at it, though, is that 30d6 is a "deadly" trap. Only one trap naturally occurring has a 30d6 damage, and that's a deadly electrical. And it's base reflex save is 28, the highest of all damaging traps. Most deadly traps have around a 24-25 DC.
Deadly traps are expected for pre-epic content (CR 16-22ish depending on variety). Epic traps deal up to 60d6 (electrical), with DCs up to DC38 (Fire), both affecting multiple characters and permitting Reflex-Half and Evasion (So potentially 360d6 total damage with Epic Electrical).
They also have a Set-Trap DC of 65 (So it is reasonable to expect a dedicated trapper to aim for a 60+ modifier due to potentially-dire fail-by-5 consequence).
Non-epic Trap DCs and Damage were revised and fully listed by Valefort here:

Note that Epic traps were
not adjusted during the balance pass in the thread, but the curve between pre-Epic traps was smoothed.
A 30d6 Hunter trap would be 5d6 more than a Deadly Spike trap (25d6, DC15, Ref-half/Evade-0, single target), making it at full investment equivalent to what a Fatal Spike trap might be.
There does exist an Epic Spike trap, (the Epic Beast Trap available from the merchant in Beregost), but I do not know the damage or DC.
