Assassin armour runes....(help)

Is it a good idea to use all my armour runes on extra energy storage and regen? (as an assassin as all of the skills use energy)

Thanks

Next time put all your questions into 1 post, keep it nice and organized.

Anyways, no and yes.
On a energy high build, take some energy runes (name escapes me)
However using survivior is best.
Most energy runes I use are 2 for a total of 29 energy, if I wan't more I'll use insignia's. Generally you take things like attunements and boost your health.

Post your build (use "card" and "/card" with the skills name in between (use [ and ] instead of quotations.)
it's easier to see where you would need the energy and give you better feedback.

Short Answer.

Survivor Insigna.
If you need more energy use +5 daggers alongside your 15^50 ones.
Use high critical strikes to help manage energy.
