Bloodhound's mark shoudn't have full dex requirement

It's pretty simple: bleeding is an ailment related to physical damage, with (almost) all related nodes being in the Str/Dex portion of the passive skill tree.
Herald of Blood is an Str/Dex skill gem and most of the bleed related support gems are Str related.
I can understand that the bleed spear skills require Dex (even thou spears require Str and Dex). But Bloodhound's mark, being a "generic" skill shouldn't have a full Dex requirement.
It should at least be a hybrid Str/Dex requirement, such as Freezing Mark has a hybrid Dex/Int requirement.
I would also argue that Vulnerability and Voltaxic mark should have hybrid requirements (Str/Int and Dex/Int respectively).
