reduce time in skills

First of all, sorry for my noobish english.



Second i have a question who is killing me...

Wich jewells i should take for get a less reuse on skills, 8 seconds on balance sometimes is not enoguth, because of the damage of the party... and what's the diference between Valakas necklase (reduces the skill cooldown) with for example Istina necklase (m. skill cooldown --%)?, and wich you would choose for a healer?. To many questions, hope someone can help me.



ty in advice :)
