I like to play all game modes so i can't go for pure heal or pure damage, maybe later in the game i'll have enought skill points and can switch between heal and damage but for now i rather focus my skill points and have 4-5 powerful skills than have all skills at low level. I know it's soon for me to worry about end game stuff but i like to set a goal and work towards it, maybe is soon to make a Crit build but not to start collecting Crit gems ^^

Thanks for your help.

All your skill planning gonna change once you hit lvl 50
You will stalled there for ALONG time lvling the main talent (IE OPstunness).
With its addition Build is out the window for both skill, gear and astrals.

But yes till u get to the 50+ range
stay with will destroyer due to limited astral space and limited gem link in trash gear.

Save the crit build for higher lvls when u have the space to link without hindering base magic attack and defense.

Oh almost forgot.
If you want to excel at both roles but the double skill tree.
Then you can focus on DPS skills in one and Heal in other.
