Change in pet behavior, "PURE" build and one-handed mechanic.

Hello!
So, i was playing with my necromancer and i notice something strange in my "pets" behavior.

= Pet Behavior:

Sometimes when im attacking a boss and a enemy hits my pet, he change his target ( in Guard or Agressive behavior ), do not know if is a bug or is how it works.
So....if is not a bug, can the devs add a "assist mode"? One that the pet only focus on my target and dont care about his defence?

= Pure Build:

For some players ( or just me ) sometimes is fun play as a Pure Sword or any of the diffent classes that the game have. But when i try to use 2 of the same combat skills, the hotbar skills mirror.

I think it will be nice be able to have the option to use all skills of a class.

= One-Handed:

This is a simple thing, if you use only your "Main-Hand" or just your "Off-Hand" you gain a bonus on evasion.

Ty for your time!
