Claw Base Types

Why are the higher level base claws strictly worse or equivalent to the mid-level ones? Unless the POE item database is wrong, terror claw is worse than eye gouger and throat stabber except for the implicit mod, imperial claw and hellion's paw have identical dps etc. This disparity in item growth causes end game for claw users to be more difficult than if the itemization was correct. Am I missing something or is this something that still needs to be fixed?

some have more dmg x-y others have less x and more Y
others have less dmg but more atk speed. etc

Terror Claw: +Double Life Leech +High DPS / -Large DPS Spread -Mid Range APS
Imperial Claw: +Highest APS / -Low DPS -Low Crit Chance
Vaal Claw: +High DPS +High Crit Chance / -Lowest APS
Eye Gouger: +Mid Range on all / -Mid Range on all
Hellions Paw: +Highest APS / -Low DPS -Low Crit Chance (Lower Level Imperial Claw)
Throat Stabber: Lower Level Eye Gouger
Great White Claw: Lower Level Vaal Claw

The way I see it there are 3 types of Claws: High Attack Speed, High DPS and Crit, Even Spread.
The Terror Claw is a stand alone.

Their use would depend on your build I suppose.
I will definately use a terror claw at 70. the -0.15 APS compared to Imperial Claw is not a big deal because I have a lot if IAS. But the extra 3% Life Leech will have significant impact.

I understand that is how it goes for most of the item types but not claws.

For instance,

Terror Claw(lvl 70) vs. Throat Stabber(lvl 60)

Both have 1.35 APS
Both have 6.68% inherent crit rate

Terror claw has a base dps of 57.38 while Throat Stabber has a base dps of 63.45. So of a 10 level gain in item, you lose nearly 10% dps.
While terror claw has a better implicit mod, implicit mods don't negatively affect other item types.

Throat stabber and eye gouger(lvl 64) also have the exact same dps, crit, speed and implicit mod. Why even have higher level item tiers if they are going to be identical or worse than the lower item tier?

And the 3% on terror claw isn't that great considering most claw builds have at least 20% LL. Base physical damage at that point is far more important to leaching than a few extra percent. And hellion's paw and imperial claw are identical except the imperial claw is <1 dps greater than the hellion paw.
