Reduction to enemy's health on skills and items

What purpose does health reduction on skills and gear serve in the game’s current state?

It used to help characters with low damage output -like tanks- to clear mobs, but with all the power creep added to GD since early access I don’t think it’s needed anymore as even the tankiest mofo in the game is already able to dish more than acceptable damage without it.

I think it’s actually a hindrance because it lowers the damage potential of the skills and items it’s tied to by adding a damage type that doesn’t scale with the player’s stats, has diminishing returns and to which bosses are completely immune.

I think it’s time for this outdated mechanic to go. This could be used as an opportunity to replace it with damage types that currently lack support ( eg adding vitality decay to Bloody Pox and Doom Bolt ).

What are everyone’s thoughts on this?
